People will drink a beer every set in a show, but they’re less likely to do that with coffee, soda, THC drink, or any other beverage except water, which most bar venues offer for free.
I'd ask you to consider the following thought experiment. If the regulatory barriers are lower to establish a nightlife business establishment without alcohol as an option, and a large number of people want to do activities without alcohol, why do these businesses not exist in significant numbers?
It's certainly not a novel concept to open a cafe or a late night board game location. If they were sustainable businesses economically, which barriers currently exist that prevent them from being present in cities to the same extent as bars?
I have no interest in a second coke or a third coffee. I can drink tea for days, but if it feels pricey I probably only have one or two. Real estate is expensive if that's your customer profile
In addition, alcohol lowers the bar for entertainment. Comedy, music, dancing, none of it has to be as good to satisfy if people are at least a bit tipsy, which makes the performers happier, and the customers happier.
Wish it weren't so (I don't drink alcohol, personally), but that's the economics of it.
