You seem to not realise the huge gaping ass flaw in your deduction.
If someone wants MORE, meaning more wealth / power. I understand the evil in this. Money is only worth what others value it for. So if someone wants power over the money, or wants to control all the pools, people will see this and the value of the money (or btc) will plummit.
Because pretty much 99% of people understand this (no offence), the one wanting power over the pools will understand it too (if they don't, they won't have the smarts to get it anyway), and thus realise that he/she will only hurt their wealth, not increase it..
Also, don't underestimate the 'power of the people'. BTC is decentralised, the masses have a huge influence.
Tadaa.
