People from less dense areas generally saw this as draconian nanny state absurdity. People who had spent time living in dense urban areas with high rise residential buildings, on the other hand, were more likely to think, "Yeah, duh, this rule makes perfect sense."
Similarly, I've noticed that my fellow data scientists are MUCH less likely to have social media accounts. I'd like to think it's because we are more likely to understand the kinds of harm that are possible with this kind of data collection, and just how irreparable that harm can be.
Perhaps Americans are less likely to support Europe-style privacy rules than Europeans are because Americans are less likely than Europeans to know people who saw first-hand some of what was happening in Europe in the 20th century.
It's better to to think of it in terms of prevention. This fits into a category of things where we know they create a disproportionate risk of harm, and we therefore decide that the behavior just shouldn't be allowed in the first place. This is why there are building codes that don't allow certain ways of doing the plumbing that tend to lead to increased risk of raw sewage flowing into living spaces. The point isn't to punish people for getting poop water all over someone's nice clean carpet; the point is to keep the poop water from soaking the carpet in the first place.
