I think that would be awesome in addition to this, but not instead of for a few reasons.
It would require a lot more prerequisite knowledge to understand what it is.
It wouldn't be much of a resource for a new user and would still require a large investment to be able to use it and feel like you're participating.
Less accessible, not on exchanges etc.

I do think it would be great and super useful, just not a replacement for a simple transfer with an association to a post/comment.
