But if history teaches us anything it is that frontiers become settled, then set, then rigidly bureaucratized, and the more bureaucrats there are, the more laws are needed to keep them fed.
And even then, kids who had grown up with Sparky still showed an interest in product tie-ins and in collecting memorabilia and old episodes. Sparky had filed that away for future consideration: surely there was a way to profit from this almost instant nostalgia when the teens grew into adults and had more money to spend.
These people do share some of Mr. Heinlein's political philosophy, the part that can be summed up as "Leave me alone!" They are not anarchists, but they brook little interference from the government. They are happiest where there is no government, and you'll find many of them, or their, sympathizers, in the more remote regions of the system. But a lot of folks can't take that kind of isolation (me, for instance), and so live well concealed (if they are doing illegal things) or openly (where they work for a quasi-libertarian form of government). They don't plan to overthrow any governments; that would be entirely too much trouble and, as even the most doctrinaire of them will admit, the yoke of present-day governments is not intolerably onerous, when viewed historically. Things could be worse, and would likely get worse if there was a lot of radical political agitation to suppress. Don't look for Heinleiners to be publishing any manifestos, nailing any lists of demands to courthouse doors, storming any Bastilles.
