If you start with the premise that the government is hostile by default, it logically follows they will get some capability they didn't have before or increase the one they had. You will have less chance to fall through the cracks and the friction you get from not having the convenient thing is a proof that the beast is at least partially crippled.

It's very often that government has a capability to retroactively assemble a very detailed information about a specific person, but doesn't have a capability to proactively screen the whole population and implement policy.

Illegal immigration is a good example of it -- when somebody is already sitting in a van it's possible to figure out whether they are a citizen or not and maybe even find pictures of watermelons on their phone. It's however impossible to selectively block phone numbers and bank accounts of all the people who are present in the country without government authorization.
