People are feeding off of panic and constant dread. If you don't affirm their apocalypse delusions you'll be shamed.
You'll be told attending a concert or even wanting to is a sign you're a selfish misanthrope and idiot.
They could just indefinitely stay locked in their home if they feel the risk is that grave...but no, they'll stop at nothing to extend their agoraphobia to everyone.
Sadly, selfish people will abuse this. They'll go even if they feel sick, likely justifying it as "but I already bought my ticket". Asymptomatic people will also increase the risk.

Anecdotally, a doctor I went to recently told me that the standard swab test is likely to be ruled invalid in the near future, he referenced a study that should be published soon.
So, we will be flying blind if large (indoor) events re-open.
Wear a mask, wash your hands, try to keep some sort of distance with people, don't go if you feel sick and try taking care of your immune system as much as you can before/after. Expect people having some sort of respect and do the same. Outdoor events would be a much bigger yes compared to indoor (note: concerts doesn't mean stacked onto each other's).
Of course, tests must be ubiquitous and this shouldn't happen while in an area having a peak of the epidemy. Restricting contacts with fragile people would also be wise.
I've been to hundreds of concerts/events and rarely been sick after one. Risks to catch a disease are in my opinion not higher than public transports or a crowded beach and probably lower than bars in general.
We need to stop this non-sense.
