You can't leave unprotected access by law, because you, as a camera owner, are responsible for personal information stored as a record. If you talking about hacking, I wouldn't worry too much -- anything can be hacked and there are much more cost effective ways to obtain personal information in millions than hacking cameras one-by-one.
I wouldn't worry/care about individual hackers, but even if you have complete trust in everyone who has or will have legal access there are a lot of organizations for which hacking cameras one-by-one (even if hacking is actually needed) is well worth the effort.
You have a messed-up idea of privacy, there can be various degrees of it and having a few people see you in a certain place at a certain time has a slightly different impact than having someone (potentially) analyze what you do in a large amount of your life, even if that happens in "public spaces".
I know your idea is the same as that of the USA law, but that really doesn't make it right
