There is no reasonable method to have a travel ban within the United States short of isolating regions by military force. At the individual level the only guarantee is imprisonment which is the not so nice way of saying you cannot leave this facility. This still requires people to volunteer to be tested!
Voluntary travel bans are only as good as the person applied to, especially in an age where self entitlement is near an all time high. Then throw in the malcontents who will just expose people for whatever irrational reason they want.
Even if we could test at point of departure what does that gain us? Say you could test at the Airport, you are positive, does the tester get taken off the line, how many people before and after? Everyone on that concourse?
