I would just say that it must be in that order:
Abolish government, then public borders along with it. Those trying to abolish the government piecemeal starting with the border are fools. Entitlements, services, enforcement, THEN the border makes a stateless society. Rearrange any of those you create chaos. Either way, this is all a mental exercise because the governed never abolish the government. The only hope is a strong alternative to make the government obsolete and ineffectual.
