There is probably some critical mass where this would work. Some people would pay to be able to just not have to do combat with the whole world simply to enjoy the Internet.

It would also make is possible for larger companies to attest to purchases made and / or the quality of participation within their community. Imagine a scenario where I donate $50 to an open source project using GitHub Sponsors with my domain as the identity and GitHub attests to me spending that $50.
Over time, it would be possible to demonstrate a significant "investment" in your domain validated identity and it would be done by spending money online like you normally would without any additional cost. The attestation that you spent the money is simply a side effect of something you're already doing, but it's a really good indicator (over time) that you're a normal participant.
At the very least, I think having a domain as a globally usable handle would help to reduce impersonation which is a serious, difficult to solve problem right now.
In fact, it would give yet another reason to hijack a domain.
In fact there might be significant overlap between something that can support a monetary system and something that supports trustworthy communication. The best you could hope for by solely focussing on communication is that it doesn't collapse under the pressure of having to keep financial transactions secure. Except any secure form of communication is probably going to be used for transactions of some kind at some point.
I can imagine using levels of its trust model to handle the levels of email I receive e.g. this domain has X validations and my friends haven’t blocked it.
