"Regulation" in the old sense of "making regular", perhaps. Establishing fair weights and measures, preventing fraud, etc. Ensuring that individuals are free to trade and that all transactions are in fact voluntary (including, most importantly, transactions with the government itself). But when your "regulation" consists of applying force to micromanage how people—shareholders in this case—employ their capital for the benefit of some other group, you've moved well outside the realm of the free market.
