It's natural for the government to want control. It's literally what it is optimized for - control. More control is always better than less control. More data about subjects always better than less data. What if they do something that we don't want them doing and we don't know? It's scary. We need more control.

> they'll need control later on when they start doing seriously tyrannical things.

You mean like when they start jailing people for social media posts? Or when they are going to ban kitchen knives? Or when they're going to hide a massive gang rape scandal because it makes them look bad? Or when they would convict 900+ people on false charges of fraud because they couldn't admit their computer system was broken? Come on, we all know this is not possible.
