The founding fathers realized that the government will externalize all their costs onto the population unless they are restricted.

The US of course famously disregards the first amendment every chance they can get . At first it seems logical stop people from airing their grievances/fantasies and less people will be inspired to commit crime. But this creates a kind of pollution of the mind and society that prevents change. A healthy society pays the social cost of crime. Whether that be faster response time, repairing infrastructure, diversifying assets what have you. It's no coincidence that younger generations increasingly accept political violence as normal as speech has been further restricted. The more invariants your system has the harder it is to change, it's in the name.
