I see where you're going, and I like the general direction, but I won't agree with "No? -> You are wrong."
A major strength of human society is its diversity and individual specialization. Everyone needs a different job, so that all jobs get done. If I imagine a work where everyone does the same job, it will result in mayhem because other important jobs don't get done. But that doesn't mean that every job is wrong.
That's the thing about these people who don't own much more than a MacBook Pro. They talk like they're some kind of buddhist monk with their minimal life but in reality they're relying on the consumerist society (dining out, using only disposable stuff, etc) and have a much bigger environmental impact that if they owned some cookware to cook their own food for example.

Do you define the current state of the world as "working"?
You'd be better to say "if more people in the world did what I do, would things get better or worse".
It's not my birth-function in life to perpetuate the way society currently functions. I didn't sign some kind of contract that says I will make life decisions to make sure things stay the way they are now. If I choose to work less, and consume less, that's entirely my choice. If everyone did it there would obviously be impacts, and things would change, though nobody has ever convinced me that society wouldn't be better if people had more leisure time and less stuff.
>>Always, always, always ask yourself the following: if everyone else in the world would do what you do, would the world still work.
The sun would still rise tomorrow. Supposed time as we think to know it really exist. Some people say that there is not such a thing as time and we all are one. In this case everybody is doing what he is doing. And the world seems to work for me.
There may very well be steps to sustainability that should not be continued in the long term or for more than some people. Should the president resign because the world couldn't function if everyone could veto things?
Yes? Ok, keep going. Maybe you have something to teach.
No? Change, you are wrong.
