You make the valid point that signature "features" (biometrics such as pressure) can be captured rather than just the static image. But to have an acceptable FAR / FRR (false acceptance rate / false rejection rate) there must be a number of such features .. rhythm, flow, sequence of "dotting the i's and crossing the t's" etc.   Typically about 16 features are used for discrimination.

Just reproducing a static signature image attached to a form offers a false sense of security.

What is to prevent it being captured by a sniffer and added to a form without the owner's permission?

How are disputed signatures managed?

So it is a deep subject and only really worth debating where there are significant risks such as medical privacy or financial privacy.

Here is one blog on the subject ..
