As I get it, there are two ways to look at the problem: 1. One is if we say that a person has a right to remain private and retains right to their image under any or some circumstances. 2. Another is if we say that a person has a right to observe and record their observations freely, always or under some circumstances. Both are highly subjective, especially when it comes to particular conditions - that's for sure. Both could be true (or not, some may argue), and in practice they're kind of balanced - but with different places valuing one thing over another, creating a different balance. Whatever an individual may like or dislike doesn't actually matter, except for being a data point - those in power (be it a power of democracy or authoritarianism) define the rules. If someone doesn't like the rules of the place they live in - well, there's no definite answer to that. Sometimes the ridiculous "live somewhere else" is the only practical answer (no jokes or sacrasm intended).
