I would say in both cases it's the government exhibiting control over its citizens lives under the notion that it's for their own protection. I think everyone has a point at which government control becomes tyranny. For some it's lockdowns during a pandemic, for others it's time-limits on video games. Seems like all apples, to me.
Your kid playing videogames 12 hours a day has no impact on my life. You giving me Covid does. These situations are not the same and the complete lack of nuance on when government authority is good and needed, and when it is bad and harmful is...well, I don't have the word(s), perhaps disappointing.
I don't get the desire to see everything as black and white and boil everything problem down to a slippery slope fallacy.
One could absolutely argue that kids playing videogames 12h a day has an impact on your life, because if every kid spent their time that way, society would crumble in a generation because young people are choosing to play games instead of work.
The topic in question was whether Covid restrictions has made people more comfortable with other authoritarian measures which are implemented to benefit society as a whole. I actually think it's a very apt point and I'm surprised you don't see the connection.
Authoritarianism often comes with a good reason, in a moment of crisis, such as war, ethnic tensions, etc. The problem is getting rid of it once the crisis abates. Power tends to work on a ratchet.
If you are only looking for a cartoon villain and not, say, yourself, you might be caught flat footed when it arrives at your door.
Okay, but this example doesn't really apply here as we've already seen what relatively limited restrictions were imposed rolled back across states and localities to varying degrees. It doesn't have to be so dramatic.
