The troll's plan to privatize highways and everything else would give companies a free hand to run them into the ground.

The deals would probably be set up so that there is no way to undo them without paying the companies 10 times what they put in. We might need a constitutional amendment to make it easy to undo them. Or perhaps a new form of eminent domain can be established for taking back anything that was privatized, in which the temporary private owner would get back the amount that it paid, minus however much it has extracted from the property since then.
