That's a point one would have to discuss. A small one time fee would be
okay, but not to much, ore we are at the same point like in X.509 land
and nobody wants to invest, except for real good reasons.

Exactly this is the point where the key signatures get in place. You
can decide whom you trust, or not, and how far your trust goes.
Than you can see, if somebody you don't know yet is trusted by a user
you trust. Then the trustdb comes into place. Exactly this is how PGP
works. PGP is not a replacement for the X.509 infrastructure like it is
used in companies or other organizations. And even there often PGP is
enough, at least for Email signature or encryption.

I'm still not sure what you're trying to achieve. A Replacement for
