I think it is an example of great preconditions for starting a company, even though it will be very challenging to make it work well. Basically, our technology is advanced enough to do this, but it so complicated that the percentage of people who can use it, rounding to the nearest, is 0%. I see it as similar to the situation with Dropbox when it was started, where it was possible to accomplish the same thing yourself -- if you have expert level ability in that specific area.

Observing how people get along with cryptocurrency wallet software, key management is a hurdle that many will fail to clear.

What you're saying is precisely why I'm saying it's a usability problem, not a technical one. We have the technology, yes. This company is not that technology. The company we should fund is the one that solves the usability problem, not one which moves the goalposts to a different centralized point of failure.

The ideal solution would look like the ApplePay protocol - there is a PKI and cryptographic authentication, but users (and receiving vendors) never need to know what a digital signature even is. I agree with you that trying to get users to handle their own key management is a complete non-starter.
