This is a much less cool post when you realize that the Earth can only sustainably support 10 billion people if we never fly, give up a lot of our modern tech, and have rice make up 50% of our diet. Basically any meat is completely off the table, as with personal cars, and probably standalone houses. If I'm given the choice between not having kids and not flying to see my family for holidays, I'll take the no-kids option.
So basically it's perfectly fine? But for some reason you made it sound horrible?
So let's build lots of highspeed rail? We went to the moon on less compute than your cell phone and modern tech could be way more sustainable if we properly optimized. Rice is fantastic and works for a significant chunk of the current population just fine. Meat? Just gotta grow that protein in other more sustainable/efficient ways. Cars are useless in a dense urban environments and make everything worse. Fuck cars. Standalone houses are a giant waste of space and when you design your neighborhoods around this idea, everything is too spread out to actually have proper density and utility.
This is a very cool post that does point out that all of these things are in such excess. You should give StrongTowns and NotJustBikes a watch on youtube for much more on the topic of urban design.

Aviation is about 2.5% of global emissions.
In the long run then yes, we need carbon neutral fuels, but it should be possible for people to fly a little and not destroy the planet.
The reason why aviation emissions are so bad is not so much the amount but where exactly they are emitted.
Which gives me huge misgivings about the current space push.
