The reason for using the payment processor as an example was to show the motivation for VC investments that will require identification/verification at the individual level. Voltage cites nostr as one of the fundamental technologies that they're building the payment processor on. If you look into Voltage, you'll notice that they're setting up individual lightning nodes to map keys to a DNS that has a valid SSL certificate.

A payment processor that allows for anonymous transactions to occur on a large-scale will not be allowed to operate. VCs are not going to invest in a technology that's unlikely to make it past infancy.
