I would love to 'live and let live', but the number of deaths is approximately 1% of those infected, so with an infection rate of 50,000 it is quite reasonable to expect 500 deaths, which is why it has been so critical to try and reduce contact between people and it is now starting to show infection rates travelling in the right direction.
Globally it will be necessary to find ways of coping with COVID long term, but until the vast majority of the world's population have been vaccinated we will still need to have enhanced cleaning regimes, compulsory mask wearing and social-distancing as an absolute minimum. Initially it is also likely that localised restrictions and lock-downs will happen relatively frequently quite randomly in different countries, so there will certainly be the continued risk of short-term cancellations and disruptions occurring at very short notice.
Thinking positively, I don't think it would be unreasonable though to hope for a very limited amount of leisure travel within Europe later this Summer/Autumn (don't forget, capacity at many resorts will have to be limited too), with a similar situation next Winter, but perhaps returning to closer to normal by the Summer of 2022.
