Hum i think that there will be a lot of broke clubs/bars/venues. I am not sure if the cultural sector really gets the help it needs. But people will party again when the lockdown is over. Already last summer it was possible at some places.
Here in Switzerland the Clubs (up to 100-300 ppl, depending on the region) opened last June and stayed open till the end of October. I remember the first Party was very surreal and afterwards the ambience depended on the venue. The max limit of guest was the only regulation, except that in the beginning the clubs had to close down at 12. There were no masks or anything else.
In France there were a lot of openair raves last summer. Gatherings up to 5k were legal, and in Paris there were like 2-3 events like this one every weekend: Possession Techno Open air 2020 - Sunshine (01.08.2020) - YouTube.
The free party culture became quite powerful as you can see during the demonstration against a new law last month: Rave party géante place de la République - marche des libertés (Paris 30/01/2021) - YouTube
I don’t really see why this shouldn’t be possible again in 2-3 months as it seems that the worst is now behind us. There will always be raves partys and raves, because there is a huge demand. But maybe there will be new organisers, because the old ones might be broke…
But for sure nobody knows the future. If we are unlucky there is another wave. But thanks to the vaccination and the other immunes.I belife there is hope, that the end of the measures in near.
