I think the way the left's exterior reproduction's been successful is by leveraging the market more effectively. By that, I mean that global capital has already done a great job of mapping and stratifying our desires. If you like, say, passive media consumption combined with power fantasies (e.g., the superhero movie), the market will figure that out pretty quick. The left then only has figure out how to inject their social reproduction program into this pre-existing channel, then reap the rewards.

Your counterexamples are indeed the succesful defenders, the ones the right could learn from. The Amish (the only successful resisters of brood parasitism I'm directly familiar with), don't have to worry about capital mapping their offspring's desire because they have created an effective cultural barrier from it. No doubt many young Amish would find superhero media alluring, but movies, TV, and phones need electricity, which they have forbidden from their personal lives. More generally, the hierarchy of God, family, work, then finally self is fundamental and encoded into the child's being. To electrify your bedroom is to no longer be Amish, which has a lot more friction than drifting from your parents' mainstream conservatism.
