It is totally unnecessary and puts a target on you that you are involved in bitcoin making you $5 wrench target.
From the OP I stated clearly that it is only when I am with my fellow bitcoin enthusiasts, so in that sense I don't see anything wrong in it.
Also, controlling 'everything' is different from having majority stake which is what 51%+ means
51% hash power rate means that a particular individual or institution has majority mining power or computational power over others in the bitcoin network, so how is that not a form of control? Imagine the individual with this 51% hash rate sends a coin to someone and a merchant accepted the payment then he secretly mines another chain entirely where that transaction didn't occur. Recall that this miner has the higher computional power so the chain can become longer than the honest chain and you know the network usually accepts the longest chain. If this happens the original payment will dissappear from the network. So in this sense I think it is control, correct me if I'm wrong, I'm here to learn and improve.
