No. It's irrelevant.

We're talking about whether you can prove that

U_n=1^oo {1,...,n}

is finite. I'm not switching topics to paths in trees (despite the
fact that the ignorance of your question is obvious).

You're playing your usual little game of trying to change the topic.
I won't have it.

I take it that this new tack is so that you don't have to concede the
point: there is no mathematical publication which claims that the
above union contains elements larger than any natural, nor any
publication which claims that this is what it means to be infinite.

If you want to discuss paths in trees, we must first finish this
point.
