I wouldn't use NEETs and hikikomoris as an example, they tend to be miserable and never have sex. Not saying there aren't people withdrawing from the system and still having lives though.

They protest their workplace pressures by doing the absolute minimum amount of work possible

Yeah thats been me a few times when ive already quit the job that im doing but i havent told anyone else yet (i think everyone has been through that)

I spent 3 days on a beanbag in a building managers office a few years back collecting a paycheck waiting for an appropriate go fuck yourself moment.

Sounds a lot like what MGTOW philosophy is about. Some try to minimize their tax contribution to the system and live minimally.
