It's quite simple: European states require serious restrictions on liberty in order to do the incredibly unpopular but morally good things they feel they're doing.
One of the weirder ones was up until ~2021 it was illegal in Germany to display the YPG flag (that is you would get stopped by police but not necessarily prosecuted) but not to engage in YPG activities.
The notion that states are the perfect reflection of the democratic will is quite silly.
Suppose a party in Europe is elected on the premise that they will provide free ice cream for all. This is an important issue for people, so they vote for the party. When they get into power, they ban ice cream to promote "healthier living".
Most citizens do not support this policy but they did support the government being elected due to various leveraged mechanisms, such as political polarization, identity politics, laws, outright lies & manipulation, etc.
Ironically, these states keep turning over their leadership because it's incredibly unpopular and the new leadership just continues to do incredibly unpopular things.
>This reluctance extends to different types of platforms. Only around a third would be likely to provide age proof for messaging apps (38%) or social media sites (37%). For user-generated encyclopaedias like Wikipedia, half (51%) say they would be unlikely to submit any proof of age. Just 19% say they would be willing to submit proof of age for dating apps, lowering to 14% for pornography websites.
