In order to free the market... (Score 1)

it was necessary to regulate it. Without limited effective regulation, such as requiring this stuff to be labeled, it can be hard to conduct fair, non-coerced, transactions. I am not saying we should outright ban the stuff -- what if somebody is in a situation where the choice is grow this, because nothing else will? But it would be nice to make an informed decision.

Either regulations, or de-regulation, can go overboard. What was right 10 or 20 years ago may be too much or too little now.

Any sufficiently advanced monopoly is indistinguishable from communism. Some guys in a room on the central planning committee decide production for an entire industry, and see to it that there are no questions from the populace.
