Life is more complex. I do not live in a society that ia that socialiatic. I worked 26 years then said FU and probably will not work again. Money is more or less meaningless now. How is that different?

On the otherhand, my grad school was 100% paid but I also worked hard. I did not do it to make money nor did I need to work to pay for it.

Jusr pointing out money is less of a motivator then one might think.

Set it up so those that don't work also don't get enough money to do those fun things.

Enough to not die, but not enough to live.

Drugs and alcohol and other non-necessities generally are not free. So I am not sure how you’d fund those things or the partying, depending what that means to you.

But if you choose to do that nothing would happen, society would support the costs of you having safe (although likely fairly frugal) housing, sufficient food, and medical care. There are already people who live that way but without the food, housing, or care; they may resort to crime to meet their needs (negative affect on society) or may just have such poor health that they require much more expensive care (already at the cost of taxpayer in capitalistic society) than they would have if they’d been able to access care before it became a dire emergency.

Research generally indicates that capitalist societies already pay more to address the consequences of poverty than it would cost to provide those people with their basic needs in the first place.

What's your definition or idea of a "socialist economy"?

I don't know if you're looking for something historical, but in the GDR you'd be thrown in prison. Refusing to work was considered asocial behavior.
