What I’m hearing is: guy gains wealth and cultural capital, realises he is steadily approaching the echelon of society that the police actually protect, decides they are not so bad after all, and now wants privatisation of police so that he can build a personal army.

Like sure it can be argued that policing as it is right now has some benefit to social order, and it definitely can be argued that the situation can be improved. On the latter point, calls to defund/abolish the police are a valid means to that end. Yet OP for whatever reason has decided that the only real solution is literally that libertarian cop copypasta.
