This seems uncontroversial - open borders in the absence of a command economy and full-spectrum welfare ie national-healthcare-style state is decidedly pro-market, pro-freedom, and pro-peace.
Certainly open-borders are as intrinsic to crypto-anarchism as diversity-of-tactics. That is certainly uncontroversial. It may be that some self-described cypherpunk might decide to advocate for border controls for some reason. The onus is then on them to prove their case. Such as in Jeff Berwick Vs John Galton However no crypto-anarchist will be caught dead arguing for nationalist borders; I promise youse.
