I disagree with most of those arguments in the article… Additionally, there is nearly no passkey using service that does require you to still have PW and 2FA login active even if you use passkeys

We are right now in the learning/testing phase. It is not a flip and suddenly only passkey work. Transition to passkey only will be a very long time, like it was for 2FA, like, my girlfriend has it on, only at about 2 services, lol.

The main problem I have is, that people without knowledge get grabbed into walled gardens using passkeys. People with knowledge know that you can use alternative apps for passkeys, like proton or strongbox (keepass).
