Not everyone is a soldier in your ideological (and literal in this case) war. People can have nuanced views for nuanced reasons.
Practically they are required for many domestic tasks, and Russia won't let you leave the region with a real passport so you need one to get out. The European Union has emphasized to its member states that possession of one of these "passports" should also expedite the issuance of a humanitarian/refugee passport.
In this conflict, I agree with you 100% - fuck Putin.
On the other hand, many international organisations don't recognise Taiwan as a country, whereas in my mind it's clearly a country for obvious reasons. So I don't consider international recognition to be the be-all-and-end-all of which borders lie where.
