I agree with this. I value high-friction environments where people are encouraged to compete and fight to support their ideas, where they feel valued for fighting for themselves, rather than patronized... The real world doesn't coddle you. Work should reflect that to some degree - with some respect to being a decent person in general.

He can find another tribe that accepts his bullshit (until they eventually drop him as well), or learn to carry his own weight before being reaccepted - by means of crafting weapons or providing in some other way as you mention.

It's harsh, but real.
