However, being able to add properties to strings, and paste them into
buffer (and display them as messages, and ...) is _very_ useful.  It's
quite often far more convenient to construct propertized text outside
the buffer and just insert it.

Cut-and-paste has its own issues (and there is some mechanism in Emacs
to deal with them, e.g., `yank-excluded-properties'), but they seem to
be more connected with that particular application, than with the
underlying low-level abstractions.
