I think {lo pavyseljirna} usually does have a referent,
and so for example {lo pavyseljirna cu se ranmi} is true.

In that case, you wouldn't be talking about anything when
you use {lo broda poi brode}. A {ki'a} or {na'i} reaction
might be appropriate. But I think in such cases there will
at least be a postulated referent, which is something
referrable.

Lojban grammar certainly allows the construction of meaningless
bridi (as does any human language, I suppose).

I don't understand the question. Could you give an example?

I guess "the underlying logic of Lojban" is something
accessible to you but not to me, so it is pointless to argue
that point.

You may be reading {lo pa selcmi} as {da poi selcmi}, that's
the only explanation I can think of to explain this exchange.

Anyway, how's this:

(1) mi cuxna fi ko'a goi lo'i karda
I choose from a set of cards.

(2) mi cuxna fi ko'e goi lo selcmi be lo karda
I choose from a set of cards. (Ontologically different one from
before, even if in the end it consists of the same cards.)

(3) ko'a na du ko'e

Therefore:

(4) mi cuxna fi su'o re da
I choose from at least two sets.

I disagree with (3), of course, so for me (4) does not follow from (1)
and (2).
