That raises the question how the decision to include any particular
Signing Cert is reached. If for a frictionless use case the user
has nothing to do with this decision, how should he gain any trust
in the validity of his own personal PKI?

That's your most important selling point.

How did this verification happen? Why is it secure?
Again, I think the scheme does not answer the most important question of
how a user can be sure he's using the correct correspondent's key, if
all decisions regarding the validity of keys are done on his behalf by
"the mesh" and "a tool".
