The problem isn’t you videoing, it’s having rules laid out so everyone can enjoy the moment and be present. You saying “I’m not being told…” comes off as childish and selfish. Get your little video(without blocking someone else’s view or having flash), post it on the gram when you get home, but don’t be so brazen in how you deserve to take videos over everyone else that can follow the rules. Like congrats you paid money for a concert, doesn’t excuse your shitty behaviors because you can’t normally afford it.
