1) Trust is a human-to-human interaction which depends on being able to predict future behavior from past behavior (and often other cues, whether rational or not).
Trusting an organization is a category error. You cannot trust something composed of people who are regularly replaced every few years and who operate according to written rules ("laws") which they are allowed to change.
2) "as I don't do anything illegal, they won't care" - This is a fallacy. First, they can absolutely harass you even if you end up winning in court eventually. Second, what is legal and illegal changes over time. Third, plenty of things which are illegal (wrong according to legality) are not wrong according to morality (they harm no-one) - they are just illegal because humans who feel the need to control others wrote down a piece of text describing punishments for them.
3) Plenty of countries have stupid laws.:
Example 1: it's illegal to approve illegal actions - which basically means you can't ever argue for to change the law to make something legal because you'd be approving it. Usually it's not enforced as such but given how the law is often phrased, it often can be.
Example 2: it's illegal to endorse the use of violence - this is the stupidest law there is:
- It is by definition contradictory because all governments base their power on violence[0] so according to this law you can't support the existence of the government itself.
- It's contradictory in how it treats historical and current actions. You are free to celebrate the assassination of Reinhard Heydrich, The French Revolution or Us independence, even though they were all violent actions - they were morally good but illegal under the laws at the time. But you can't say that current dictators should be killed. A friend got a warning from reddit just yesterday for saying not that a certain dictator should be assassinated but that he should be sentenced to death and then executed by anyone in a position to do so.
[0]: The government has such a strong monopoly that the violence just needs to be implied and most people will submit and the rest are used as examples "this is why it's stupid to fight a cop".
