The difference now is people are hyper aware and that is the test in the coming weeks. It's already been proven that lockdowns are totally unnecessary if everyone socially distances correctly which obviously wasn't the case prior to the lockdown.
Lockdowns are only put in place to ensure that the NHS is not overwhelmed by the influx of cases which currently is slowing to normal levels. If everyone follows the rules then there is no reason why at least some things can go back to normal.
Obviously in places where it's impossible to socially distance, there's no chance they'll come back and I'm afraid that means pubs etc. The pubs aren't going to open anyway if they can only fill the place with 1/4 as many people.
