We have to differ here just a bit. Your concerns are all correct, but speaking as the owner of 3 sport horses that compete all over the US and who often leave the farm for training, shows, etc, or just to hack out across neighboring farms, the paperwork necessary to just go on a one hour hack across 14 other farms would be prohibitive, expensive, and just lead to noncompliance because of the onerous nature.
The government is deep in the process of facilitating a fascist state.
Real good points my friend, I was not aware of the details you bring up.
