Because explicit hierarchy is almost always better than implicit hierarchy, which is what happens at a "self-organizing" company. A company may start off with good intentions but without some hierarchy past a certain size or tribal connections (e.g. friends and co-founders), then either:

a) Progress slows to a crawl with everyone trying to reach consensus on everything. This also leads to less accountability.

b) Everyone doing their own thing leading to an operational mess and constantly repeated work.

c) An implicit power structure forming and working behind the scenes which then breeds an atmosphere of paranoia and stress.

I'm reminded of these tweets about Valve from Richard Geldreich: https://www.reddit.com/r/valve/comments/8zmp07/former_valve_...
