Agreed, notary is the ultimate scam. Folks who collect $$ for putting their seals on documents in a profession where supply is artificially constrained to be like a monopoly
It's not a scam, it's just inefficient. The reason a notary is so expensive is not because their work is difficult, but because they are liable for the validity of documents they stamp. It's kind of an insurance for the customer. Which won't be needed anymore for algorithm-based notaries, of course.
