I understand what you're saying, and this is just not the place in which to elaborate effectively about the subject. Drinking beer in and of itself is not the point of contention, it is more specifically what some people do after they drink the beer that is the problem leading to regulation. I can't imagine anyone who might take offense at seeing you consume a beer in your own home calling the cops to complain. What I see as a more likely event would be someone hearing a stereo system wailing away at 11:00 pm, looking in a window of the house where the noise is coming from, finding those inside drinking and making merry, and then calling the cops, who cite the homeowner/occupant of the house causing the ruckus with disturbing the peace, etc...
It isn't necessarily the act itself that gave cause to the regulation, but the outcome that effected others that promulgated it.
As for the slaughtering/dairy issue, I agree that the realities of government allow for abuses such that the little guy gets stepped on while the industry gets away with murder. I've fought the good fight at city hall to try and correct some of that a long time ago, with mixed results. The bottom line was I was allowed to slaughter goats privately so long as it was not on public land or within the city limits. I found that accomodating enough for the amount of effort it took, and while it was a compromise, it did give me at least the option. That was smalltown, USA back then, though. I doubt you'd have any hope for success changing the regs in somewhere like Milwaukee, Chicago, or Knoxville. The industry lobbies are far too strong there. I worked at a slaughterhouse and was amazed at what they could get away with and what they absolutely could not.
Still, there is much that could be said to continue this discussion, but not here. I wish we could sit over a few beers somewhere, either your place or mine, and hash this out; I bet we could both learn something.
