If I can choose it to be a Norwegian prison, may be 100-200k USD. I always wanted to take a self-discovery retreat but can't commit to it.

Depends on a jail. Some are more like resorts/rehabs compared to others. US jails for 6-month crimes aren’t particularly bad, afaiu. Personally I’d take around $200k too for a US jail, assuming I have nothing to do for half a year and there will be no social/legal consequences that matter.

Disclaimer: I wouldn’t commit a crime to make money/time tradeoff, only a hypothetical experimental exchange with no real danger to anyone.

This "what if" is not realistic, because you have the retainer of "there will be no social/legal consequences that matter".

A felony prevents you from getting a job. Obviously being hyperbolic but you know that the conviction is as much a punishment as the incarceration.
