But then you have a brilliant idea. If instead of you choosing a specific number, you independently uniformly choose a positive integer n, the probability of you winning will be at least 1/2 by symmetry. Thus a situation with two independent countably infinite fair lotteries and a symmetry constraint that probabilities don’t change when you swap the lotteries with each other violates independence conglomerability.

なお、関連 検索 a countably infinite fair lottery で、下記ヒット ノンスタ使って、うんぬんかんぬん。でも、”1/2 by symmetry”は出てこなかったので ダメみたいですね

Abstract
This article discusses how the concept of a fair finite lottery can best be extended to denumerably infinite lotteries. Techniques and ideas from non-standard analysis are brought to bear on the problem.

P2
Remark. When the number of boxes is finite Player 1 can guarantee a win
with probability 1 in game1, and with probability 9/10 in game2, by choosing
the xi independently and uniformly on [0, 1] and {0, 1,..., 9}, respectively.

Sergiu Hart氏は、ちゃんと”シャレ”が分かっている（関西人かもｗ）
Some nice puzzles Choice Games と、”おちゃらけ”であることを示している
かつ、”P2 Remark.”で当てられないと暗示している
また、”A similar result, but now without using the Axiom of Choice.GAME2”
で、選択公理なしで同じことが成り立つから、”選択公理”は、単なる目くらましってことも暗示している
