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.
