As warning, not as victim blaming, I'd like to point out that you should never ever risk money that you can't afford to lose on high-risk investments. Especially not extremely high risk stuff like cryptocurrencies, NFTs and similar scams.

I am of the mindset that non-violent offenders, should not suffer a life penalty regardless of their alleged crime. They played a game and lost, they should not lose their head as well.

A game with whose stakes?

Hear me out, what if we allowed people to access health care regardless of who has how much money?

While your direct point is valid (for the US), you're missing the general point.

Money can be tied to life changing/life threatening events or situations in many more scenarios.

The archetypal scenarios are people losing college money, retirement savings, downpayments for their kid's apartments/houses, etc.

There are many ways in which money is very, very real.

Anyone who still clings to this "fiat" thesis is just detached from human reality.
