The issue with the comment I replied to is that it takes individualism to mean something like isolation, which is a straw man when that position has no advocates.
Individualism is something more like individual autonomy, which is in no way incompatible with individuals entering into voluntary associations with other members of the community -- as long as no one is forcing them to. But that's the thing we've destroyed through regulatory overhead and vertically integrated monopolies which force people into associations with entities they'd prefer not to be associated with and deprive them of their autonomy.
