It isn't like prohibition because Patent and Trademark laws have been around for a very long time. Why do you think it is okay or "fun" for someone to have an idea, to market that idea, to spend millions and millions to advertise that idea, and then someone else can just ride on the coattails of all that work and make money by "copying"? It is illegal to do that. It isn't an issue like smoking to me.. counterfeiters make a lot of things besides just purses. They make fake drugs and they make them in ways that it is unsafe to consume those drugs yet they get into the hands of unwitting consumers. Maybe the new decade has brought a different level of morality that believes laws should be upheld.. who knows. If we legalize "copying" other peoples ideas why would anyone think any new ones up? If we could just keep leaning on others ideas and making money off of other peoples hard work then eventually we would stagnate as noone would have incentive to think any new ideas up.
