Right you got me thinking so here's my thoughts. Not looking to argue just discuss the points you've made.

1st paragraph:

Global economy crashing is a good thing. Like you have pointed out it is completely dependent on a non-renewable resource on top of that it is one of the biggest contributors to worldwide exploitation. It also a contributes to cultural colonialism.

When it comes to farming. People will come up with solutions. I believe that farmers are competent enough that when we run out of oil they aren't just going to go. "welp guess I starve now". They are going to innovate and do what they can to keep going. Also swapping out an ICE motor for an electric one doesn't seem that complicated.

Also Interesting that you didn't mention plastics. The most used oil product in the world. I'll be so glad when they're finally gone.

2nd paragraph is just a continuation of the first.

3rd paragraph

The key word in this paragraph is make. We don't really need to make any more electronics. We've already made enough. How many processors do you think are just sitting in some warehouse never to be used because a newer model came out. How much of those precious metals are inside cars that are going to be useless once oil runs out. We need to focus on recycling and reusing existing things and devices instead of making new ones.

4th paragraph

Water is a cycle. It doesn't just disappear. We already recycle most of our water. Although I'm not that knowledgable on the topic so I can't say much about it.

5th paragraph

skip.

6th paragraph

The scientific community has made those assertions with the assumption that we are going to keep doing what we're doing. Mindless consumerism, buying and making new things, and abusing our planet. And they are right. What I and the commenter you're replying to are (probably) saying is that the problems with resources are caused my how we live our lives and the problem disappears without capitalism, consumerism and the constant resource abuse they create. A more sustainable shift in society and economics will solve these problems

Also

I sidestepped you're points about money, because I am an anarchist. I see capitalism and money as the precise reason for this artificial scarcity and natural abuse. Like you even said in you're comment even if we get infinite resources in the form of asteroid mining it still won't be distributed properly due to monopolies. Having more resources won't fix anything because the problem is the market that distributes them being inefficient due to running entirely on profit motive. The solution is to end capitalism and when we do we are going to find that we have more than enough without needing to do asteroid mining. Where would we even get the fuel? doesn't that require oil?
