> I could murder someone quite easily. Do you put me in jail just in case?

Nope, you haven't. You have the potential to attack someone and hope they can't get away in time or protect themselves.

If you really wanted to get the ability to murder someone at your sole descision, you'd have to take someone hostage, plot a terrorist attack or build a nuke. All of which will instantly land you in jail.

In the same way, I think a monopolist should be regulated because basically the only thing stopping them tovdo harmful things is their own descision not to do so. A descision that could change for whatever reasons.
