Full Idea
Maybe the singleton of something x is not an atom, but consists of x plus a lasso. That gives a singleton an internal structure. ...But what do we know of the nature of the lasso, or how it fits? We are no better off.
Gist of Idea
Maybe singletons have a structure, of a thing and a lasso?
