The NFT is a non-fungible paper that says "you own this thing everyone can use", and as soon as you make that thing private, the NFT instantly loses its value.
A land deed is a "non-fungible" paper that says "you own this thing everyone can use", and as soon as you make that thing private, the deed massively appreciates in value.
These are two entirely different cases. One is a private company not wishing to deal with a private group due to fundraising for Cuba. While that's a legal thing to do, it's also perfectly legal for a bank not to want you as a customer. If the DKP thinks they're being discriminated against, they should sue the bank. The government is totally not involved here.
The second example is a dude who is literally a paid Russian propagandist. Putting them on the sanctions list is much more effective, since they're not actually in Germany most of the time, but base a lot of their work out of Turkey. Kicking them out would do nothing.
Quite a few Russian propagandists are using the antifa label and Palestine support to get away with their propaganda work. In the case of Dogru is not even well hidden, he went straight from openly paid Russian propagandist to barely-covered propagandist without even bothering to change the name much, or the media channels at all.
