I'm in Canada. I don't need remote ID up here. And I have no plans to go south of the border.
Not worried about law enforcement. (At least, not about my flying. Very concerned about the systemic problems various inquiries about various Canadian police forces have brought to light, but that has nothing to do with Remote ID.)
Rather concerned that someone with a phone and the right app could grab my location/information and decide to take the law (as they imagine it) into their own hands — especially as where I usually fly there are other drone owners who also fly there and I could easily catch the blame for their actions. Back before we got the latests version of drone rules up here, you were required to put a name, address, and phone number on your drone. An Ottawa police officer (and drone pilot) publicly warned people about putting their home address/number on their drone, based on the variety of crazy stalkers he'd dealt with over the years.
If Remote ID was only accessible by law enforcement, the same way license plate information is*, then I would have no concerns about it. (Well, except a lingering concern about requiring internet connectivity, because roughly 1/3 of my flights are in locations that don't have any.)
