I don’t see how it is comparable to preexisting conditions. Two people using one payment system does not prevent two other people from using some other payment system.

We already have limited options with different features regarding fraud/chargebacks, like paying for something with cash versus with a credit card. Clearly both cash and credit cards can exist together.

I was attempting to make the analogy that a system designed to support both untrusted peer to peer payments and exchanges must support the lowest common denominator, the peer to peer untrusted payment which forces huge inefficiency into the system.

Similarly a health care system designed to support people with and without preexisting conditions must be designed to support the lowest common denominator, those without cover, which forces huge inefficiency into the system.

Maybe a poor analogy.

Cash and credit aren’t really analogous to exchange and peer-to-peer as in crypto the former is built on top of the latter. Credit isn’t built on top of cash in the same way, as a trusted intermediary abstracts the two concepts. To some extent they’re both eventually built on top of ACH.
