moeblee thinks:
 if x in [x]
 then all y in [x] must equal x!
Huh? There's no evidence here that that's what he thinks.
Instead it looks like he thinks that [x] denotes a set with
x as its only element (y in [x] if and only if y = x).
What else would one imagine the notation [x] would
mean, in a supposed set theory?

In a set theory, yes, that's what {x} would mean, but
in a _mereology_, that's not what [x] means.
