You keep stating that keeping animals as Pets an such is a 'Freedom'. This is part of the problem. It is not a 'Freedom' in the same way that you are insinuating. Comparing having to treat other living creatures to a certain standard, and having land taken away for no apparent reason are 2 completely different issues, they're not even closely related and it does nothing but diminish what you are trying to argue for. Keeping Pets/Using them for Entertainment and to make money shouldn't be classed as a freedom, it should be classed as a luxury that is earned.
To keep an animal as a pet, or to make money from, such as Zoo's, Rodeo's, Pet Trade etc. then of course there should be standards that have to be kept. Don't forget a choice has been made by people to try an make a living from selling these animals, or watching them for entertainment. So they should not then complain when the majority of people think that they should have to keep these animals in humane conditions, and not just be left to trade as they please.
One quote from your original post really stands out for me, an it may seem like nothing to some, but for me it points out the mentality being dealt with. You say that silly things like a Goat not being kept next door to a Lion because it knows it is going to be eaten. If you did own a Zoo and you think that an animal living in constant fear of being eaten is not an issue then I guess you had the wrong mindset all along.
The land isn't just being taken away from the humans.....
