Of course the powers that be will use any crisis to further their plans.
The direction we're going in is total access to information and the end of privacy. The "passport" that Hovis mentioned for example, to allow access to public places, has a legitimate rationale behind it. And you can say, "why would 'they' care what public places I visit?" They don't care about you specifically but they do care about the ability to access that information if it serves their purposes.
To put it simply a single policy can have the ability to be used for good or bad.
And of course, if you mention the potentially bad uses for it you're considered paranoid.
Of course, people do sometimes get paranoid and think they're being watched. Some of them might be correct. But it's not about watching everyone. They don't have the time or resources for that. It's about having the ability to trace anyone if there is a reason.
So, just as 9/11 was used to get us to enter a new world of "security" the virus is being used to provide legitimate reasons to further invade your privacy. That's just a fact. It doesn't follow that every bizarre theory people deduce from this is then true. Bill Gates probably isn't trying to inject you with micro-transmitters and the coronavirus probably wasn't intentionally created and released on the public. (They have much more effective things to release on us if they really wanted to "reduce population" or create panic.) But if you trust your elected officials and the people that they actually work for to have your best interests at heart, you're naive. If you think they won't use this pandemic or any other crisis to their advantage you're much too trusting and probably just find comfort in allowing others to make decisions for you.
