You seem to be implying that raising questions about how we do things is silly because regulation would be overwhelmingly complicated and infeasible.
However, if it's a public company, (which is just one possible abstract entity) then there are all sorts of rules and complications when there are one or more large investors.* Given these rules and regulations exist, it's not unreasonable to consider whether they should be changed slightly in pursuit of the public good.
*I'm thinking of stuff I've read about CBS v. Redstone in Matt Levine's column, where the board of CBS was trying to get rid of its controlling shareholder. They seem to have failed, but it was a fight.
