This. There really is no such thing as an entirely good government. Government is composed of people. From politicians to clerks, it's people all the way down. Some people are good, most are just trying to get through the day, and some are evil. Seriously: in any government, some of the bureaucrats and politicians will be corrupt or power hungry or sadistic or whatever.

When you give a government power, there are people in place who can and will abuse that power. If not now, then next year, or in five years. After all, power granted to the government rarely goes away.

This is the reason that you should always consider the worst case, when governments gain power. The power to ban a specific technology? What could go wrong? How could that be abused? Let me count the ways...

I'm curious if you apply the same logic to speculation markets and corporate profits.
