I think you misunderstood the purpose of this. This is not for citizens to join it’s an instance for government officials and offices. This is very good practice to prove a account is the official account.
But honestly I have more trust in my government to not exploit on me then I have in meta/Twitter.
If I understood this correct from my interpretation of the dutch server description this is an Instance for dutch government officials.
At least Germany also has such a mastodon instance too for quite a while now. So people on mastodon know that an account there is officially a government account. The BSI (German Office for cyber security) and other offices post there.
This is not an Instance for “normal people” to register on.
