"Of course it's possible, but it's nowhere near as simple as you suggest."

it is exactly as simple as I suggest.

you buy a ticket, tell your things, go to the new country.

start saving money, figure out what you want to do.

or don't, and just hang out. retire at 30.

"...living there, there are many more problems to overcome to achieve that."

not that I've encountered or heard about from any traveler, It's more of the same.

"within the EU it's doable"

or any other part of the world.

'but you're going to run into visa related issues trying to immigrate to most other countries."

whoever is telling you this is incorrect from any practical or logistical perspective and obviously have no idea what they're talking about.

moving permanently is easy enough procedurally, but there isn't a ton of benefit in going through that whole process for no reason, whereas living in a place for 6 months or a year and then living in a place for another 6 months or a year gives you all of the upsides and none of the downsides.

especially within the context of saving money and controlling your own life, what's the point of going through the hassle of applying for citizenship or changing nationality when a Visa-free stay or tourist visa takes 10 minutes?

living permanently on tourist or digital Nomad visas is way less trouble than going the citizenship route, while retaining all of the benefits.

"Some, perhaps most, of those can be overcome by throwing money at the problem"

you don't have to guess, you can just ask the question.

If you have money, it doesn't really matter because visas are way cheaper overall than the cost of living in the US. $40 for 6 months is very common.

The only time money would help is if you're trying to buy citizenship specifically, in which case there are a few less financially stable Islands that will accept $60,000 or something to become a citizen.

again, there's no real reason to do this unless you want to second citizenship, but you seem very focused on these esoteric non-issues, so there's a way that you could necessarily spend a bunch of money money if you want to.

The Schengen areas are completely free for 3 months, and you can apply for longer visas if you like.

and visas take 10 to 15 minutes to apply to.

online.

traveling is much simpler than people think.

"Even once you have a visa there are often limits on what you can do and where you can work until you get the equivalent of a green card, which can take years."

If you work online, most countries do not have a restriction on you working in their country.

If you want to become certified in that country at some offline profession, then yes you're going to have to take certification courses like in every other country and profession.

but you're coming up with this very unlikely problem, like your health concerns that are completely immaterial to practical life.

why apply for a work visa if you don't have to?

Why commit yourself to a office job when you don't have to?

Why struggle for more money when you don't need more money?

If you are a native English speaker, you can start with zero experience TEFL certificate, repeating primary colors to school children for $20 an hour.

you can work as little or as much as you want online or in the classroom, and done.

work for a couple of months, save a couple grand, reevaluate.

English teaching is by far the easiest route to start making money immediately with zero experience, but online work is everywhere in every field and depending on what country you're in, a few hundred bucks a month is going to cover you.

steve not being able to be hired as a paper company manager in Stuttgart just isn't a realistic concern.

he doesn't have that financial burden or the negative cultural reinforcement where he is forced to believe he wants to be a paper company manager anymore.

"Then there are the logistics of living in your adopted country."

absolutely! immaterial.

Google house/apartment any City, get a house or an apartment.

every country has transportation, healthcare, supermarkets.

The "logistics" is a false scare, like "culture shock", where Americans pretend that they don't understand what a bicycle is.

"your muffins are usually savory? I'm used to sweet muffins!?! brain aneurysm!"

"upheaval"

sell your things. buy a ticket.

Slough off all of your financial concerns.

call your parents with free Wi-Fi calling or your family everyday.

or take your family with you, I know families that travel permanently.

it's so much cheaper and they get to live in all the paradise places everybody wants to go to.

traveling is exactly as simple as I'm making it out to be.

I've been doing it with zero problems for years, I know people who have been doing it for decades, I know people from every walk of life who have done it, with every disability or privilege you can imagine.

it boils down to buying a ticket and going where you want to go.

The first time can be scary, but there's nothing real stopping you from taking control of your life.

as soon as a traveler moves for the first time and you land in the new country, or you go into a store in Portugal and realize that yes they also have juice and toilet paper, you realize that all your concerns were ridiculous.

everything you do in the US, you can do in the countries you live in, for far less money with better social services.
