An obvious and apparently irresolvable contradiction.
Capitalist power is inherently anarchic and isn't power at all. It's simply order emerging from the anarchy of the market. But the ability to take that power away from them, no matter how you measure it, itself falls into the category of "too much power" with wide margin. And with this amount of power there will be no change of hands that hold it.
You may be confusing some abstract unachievable ideal with the reality of the world we live in.
In reality, being superwealthy absolutely comes with a tremendous amount of power.
It is also pretty much the opposite of anarchic, given effects like regulatory capture and politicians pandering to the desires of the wealthy.
