Evolution of society only goes one way. Once the world opens up (and it's already starting to, at least at a regional level), people will start travelling again. Some will definitely be back travelling earlier than others due to health or financial worries, but I absolutely can't see staycations and not going any further than a half-day driving distance from home becoming the "new normal". Very few will subscribe to that, if anyone. Hence the need to keep the technical, human and organisational resources required for wide-scale travel ready for when it's up and running again.
