Private campground. Couldn't care less about their rules but I respect them.
If they became too burdensome, lobby to move the event next year.
Little bit of arithmetic will show the blow that is.
That's how shit works in voluntary societies that respects private property, isn't it?
Heres the problem, in a nut shell, in regard to alcohol..
Even though its private property, the public is invited. That makes it a public event, basically.
At a public event, it is necessary to purchase a temporary beer/liquor permit. (most likely just a beer permit, for simplicity, which is what you see at a bizarre or fair).
These permits must go into someone's name, who is then responsible for the distribution. Carding to prevent minors, cataloging the amount sold, probably paying sales tax per vend, all sorts of clerical horseshit. You are also then liable if someone wrecks their car and kills someone, because you sold them, maybe they were visibly intoxicated... Theres a lot to it.
To prevent the trouble of the variety of lunkheads that may fuck the dog, the owner simply denies the sale of beer on his premises. He could have insurance issues with this, as well.
If you put it on
actual private property, it's probably not feasible to have all the necessary hookups for utilities, toilet facilities, and the property owner still has the issue of insurance liability. Its a trade-off. You could sell tickets to get into a "private party", charge for cups or whatever, but the venue location itself would probably suck major ass.
The simplest solution is to just BYOB, abide the rules of the campground, and everybody's happy. How hard is it to bring your own fucking booze, y'know? Not hard at all. Its a non-issue.
People who can't wrap their head around that, and make a big kerfuffle about the alcohol sales thing don't understand dick, probably shouldn't be there in the first place.
...which is why some people are raising holy hell about the illicit advertised sales last year, and other people just don't "get it". It was a direct slap in Rogers face, and very uncool in my opinion.
If you wanna "help a brother out", and sell him a few cans out of your stash, great. Nobody has an issue with that. But if you truck in a couple kegs and just start sellin' fuckin' beers willy-nilly, I'm sorry, but you're a dumb reckless dick with no respect for a mans hard-earned property, and his gracious invitation for you to be on it.
