I can see one possible very positive outcome for Brexit:
1. Unilateral free trade. In other words, unilaterally abrogate all tariffs.
2. Visa-free travel.
Should no EU country budge on this, the UK will suffer. However, should other countries decide to also leave the EU and unilaterally go tariff-free, that might benefit the UK.
As for the second point of visa-free travel, that's primitive compared to free movement of people allowing them to even work visa-free, but it would protect at least the UK's tourism industry. It's more open trade with other exiting EU states and the rest of the world might compensate for its weaker immigration policy due to no more import tariff at all.
All of this is conditional on at least a few other major EU states leaving the EU and doing the same.
