The physical holding of a stock certificate is a dangerous thing. If you are an investor in a company that gets sold or goes public (and you have to surrender your shares) and misplace them, it is an expensive mess, even in Delaware.
In my case, I think everybody was at least motivated in the same direction. But if they had decided to put up a fight? Good heavens.
Full disclosure: I work there.
Sure, there are a few companies that it takes a while for everyone to agree on the facts (example: prior CEO raised a bunch of angel capital on bridge notes, but some notes are missing, incomplete, or not executed...) but we have a lot more companies with near 100% acceptance rate of their outstanding cap.
