If you truly wish to smash the nanny state, then don’t provide any children. If you really want to destroy society, then you must refuse to breed any future replacement workers. If you actually want to sabotage the social order, then you must reject the indoctrination to raise a next generation.
Politicians talk so much about “family values” precisely because this sort of domestic unit enslaves you to the system. While a single individual might be brave enough to resist mass oppression, a parent is always a bit more of a coward to take-on the establishment. You cannot struggle against the corporate state if you are afraid that your kids will go hungry when you ultimately lose your paycheck. The pressure to feed a family enslaves the worker, so refusing to burden yourself with offspring makes it all the more difficult for managers to control the lone individual. After all, you can’t buck the system if you are worried that your brats might be deprived of their healthcare. One you start changing diapers, you end up doing what the establishment tells you. A mother with children to support will always end up doing exactly what the boss commands. There is something about shitting out a kid that saps a parent's backbone.
I don’t care how rebellious you might imagine yourself – if you have a child to your name then you surely haven’t resisted shit. Government doesn’t care how many protest marches you might attend, as long as you have excreted a couple babies. Childrearing is always an act of conformity. Liberals who continually justify their despotism as “protecting children” – will lose a weapon against your freedom if you simply don’t have any offspring. The child-protection racket will not be able to coerce anything from you if you don’t have any bastards. All that matters for the ruling class is the harvesting of yet another generation of wage slaves. Ultimately, our totalitarian society will be destroyed by your refusal to procreate.
Mind you, this tyranny will not be demolished by having the current generation gradually wither away — that will, quite obviously, take a bit too long. Instead, the authoritarian democracies of our time will die-out because the refusal to breed children frees your mind from social manipulation. A gentleman without any dependents is able to think freely. Rebelling against the humanitarian's constant pressure to become a parent is a renunciation of your assigned social role. Remaining childfree is a repudiation of the ideal of a more perfect society yet to come.
Getting your tubes tied liberates the mind; getting a vasectomy frees your thought from communitarian brainwashing. If you refuse to spread your seed then you are damn near invulnerable to coercion. A childfree individual is not quick to obey orders.
