... so long as it does not materially impact your ability to provide basic necessities for your own wellbeing, food, water, shelter, some level of climate control, etc.

... and you are not directly, indirectly, or functionally spending other people's money on your hobbies.

No. I agree with you

Spending disposable money on hobbies is fine

I'd say spending SOME money and time on your most fulfilling hobbies is damn near a necessity for a healthy existence.

And yeah sure, plenty of people don't do that, and plenty of people literally cannot afford to do that here in my dear old US of A.

But you know what else I see a lot of people doing in the US? Fighting mental illness and talking ever more openly about the need for revolution and violence.

As long as "spending money" isn't the hobby and you actually use it otherwise it's a waste of resources.
