Large beer containers are “rare” for the same reason large soda containers are rare: carbonization. If you store an opened bottle of beer for a few hours, it will go flat, killing part of the taste with it. Beer is even worse in this regard than soda.

Every single self respecting bar has beer from the tap, right? That stuff doesn’t appear magically. It comes in kegs. You can buy those kegs from a wholesaler, or from the internet.
These kegs work by inserting CO2 to pressurize it. So you will need CO2 tanks and a system to pressurize the whole thing. Not super hard to get, but not something you find in your supermarket either. But if you consume enough beer, it can absolutely be worth it to buy a tap, CO2 and kegs instead of bottles.
