Oh. That. The problem is that some people refuse to understand recursion.

The phrase "something such that it sees itself" in English has the same
"problem": "itself" refers to what it is, but how do you know what it is until
you know what sees itself? Humans can make the tremendous mental leap to get
over recursion, however. Note the sarcasm on "tremendous mental leap", because
figuring out the meaning of {da viska lenei} is only as difficult as figuring
out what x is in (x = 2x - 3).

In (x = 2x - 3), a stupid computer program might decide it can solve it by
substitution:
x = 2(2(2(2(2(2(2(...) - 3) - 3) - 3) - 3) - 3) - 3) - 3

Whereas a better computer program or a human with any understanding of algebra
would know to consider both the "x"'s simultaneously and combine them onto the
left side.

When you say "does not exist until...", you imply that the sentence is parsed
in some temporal order. This might be the case if a very basic computer program
is doing it. However, both mathematics and human thought involve resolving
recursion. You can't resolve one part of the sentence before the other, but you
can resolve both simultaneously.

Let me try this again with a specific example:
{mi viska lo broda be le brode}. (lo is easier to work with than le.)
The pseudo-bridi is {broda be le brode} (where did I say anything about not
having an x1 making it not a BRIDI? It's not a BRIDI because it's not parsed as
one.)
{le} makes this into an actual bridi: {ko'a broda le brode}. {ko'a broda le
brode} never becomes part of the sentence. It's a bit abstract, but if you
can't understand this concept we're at an impasse.
The imaginary {ko'a} does become part of the sentence, as the referent of {lo
broda be le brode}.

The result is that the sentence is {mi viska ko'a}, with that ko'a not really
there, but referring to the same thing as {ko'a broda le brode}.

I could do this without constructing a separate bridi, using poi and voi, but I
assume that's what And is doing which you object to.

The conversation between you and And soared to great levels of abstraction. You
two couldn't understand each other, so I rather doubt I could.

If that is in fact what And meant, it's nonsense. A sumti does not contain a
BRIDI. It might contain words which would be a BRIDI if they weren't in a
sumti, but since they are in a sumti, they aren't a BRIDI.
