I think once affordable flight crafts become a reality.. it's kinda hard to control all these cross border stuff ;). What, are they gonna shoot down everything on sight?

I agree but the issue of visa will forever remain. Not for anyone who's country ranks higher in the list but for me it will haha.

Besides I think for aircrafts you need an entirely different set of permits altogether. Rea flying cars that you and I can use won't be a reality anytime soon. :P
