> signatures have immense power

In reality they don’t. You’d be astonished at how rarely anyone attempts to verify them. In fact, the only reason people still sign credit card receipts is out of habit. The truth is that the fact that you signed it, which is usually caught on video, makes it almost certain that there will be no challenge. Imagine a world where every signature needed to be verified. The world would stop working overnight.

With the advent of “smart contracts” signatures will become less and less important.
