Consolidated money is power. The only way that capitalism can work long term is if there are rules actively countering/fighting using that power to change the rules.
Money is power and capitalism consolidates money. So capitalism consolidates power. Consolidated power can change the rules in its favor to consolidate more.
The only options are prevent entities from consolidating money (which means you're risking losing capitalism), Or prevent entities from using money and power to change the rules (which, if you think of all the ways gratuitous money could be used to influence, is the social equivalent of solving the halting problem).
