The U.S. is rooted in freedom from overreaching governments. (Slavery, equality is a separate dimension). That's how we were formed. For a while we were nearly tribal and free. We got screwed over when we allowed a federal governemnt to "protect" us. The Bill of Rights was supposed to ensure we didn't lose our freedom. It should have kept us free but instead allowed key points of control like real estate tax incentives to enrich an oligarch class and now we have "corporotacracy." The recent/present leaders can not protect us without violating our rights to privacy... ...or won't.
Electric fences and RF food collars feel icky to cows in pastures that don't have them. Cows who already have them don't seem to notice.
I think added to that is that Americans have a historical tendency not to trust any kind of federal govt oversight/information collection
