It just is, the law specifies exactly under which law articles websites can be blocked, and all of said articles are quite specific about scamming, phishing, extortion of personal data, etc

Yes, but now you have established that the government is allowed to mandate such blocklists. The entire history of the world tells us that what is included in that blocklist will not remain as constrained as it currently is.

Laws are easier to add than revoke. Might be just for scam websites now (haven't checked your claim), but it's a single majority vote away for any website in the future that those in charge want to label as terrorist, propaganda, unethical, or whatever else the next group that comes to power finds as an excuse for information that is against their own agenda.

Depending how the law is implemented, it may only be a ministerial decision away.
