As long as many casinos or sport bookies offer me to bet on esports without the need to come to your place to bet on some strangers who are playing for their honor and glory against each other, I would rather bet from the comfort of my couch at my dark room where I feel cozy.
Still as an idea is a good one but I don't think it will interest to many gamblers. Gamblers prefer to play in full anonymity , what you are going to do is to destroy anonymity if you will gather gamblers at your place.
I understand what you feel, great point. That's why there's going to be an online option to make bets

To be honest, it's even better to not have gamblers in the place. Too many emotions running around and you never know what can happen.
