You miss the point.  The signature isn't being used for authentication
purposes like signing checks.  It's being used to write a form letter
to a zillion customers, where forgery is a non-issue.

I suppose that once the signature is available it could be used for
unauthorized things, but only if digitized signatures are accepted in
such contexts, which it seems they might not be.  Although, as I
think about it, I've seen digitized signatures on payroll checks in
companies where there are a *lot* of checks written every month.

Anyway, I think that lots of people use digitized signatures for lots
of purposes, and authentication isn't really the point.
