He has some radical ideas. I can't speak to that one, but I do know that his position is often misinterpreted. For example, he wants to enforce environmental laws through the courts. The headline was that Paul want to eliminate the epa, or something close to that. What he wants is for industry to be held accountable by landowners. If company X is ruining my water supply, I don't call the epa, instead I sue the company. His position is not that companies should be left to run amok, as some would claim. He just wants to regulate emissions through landowners rights and the courts, and not through Government agencies.
Is that practical? Probably not. However, as a hybrid libertarian, I can appreciate his motives.
