(one example of an unreasonable system that eliminates tactical voting is picking one ballot at random and determining the results based solely on its preferences; the precise text of the theorem rules out “nondeterministic or dictatorial” methods).
Not sure if this is covered elsewhere in the comments since it wasn’t easy to search for, but is there anything actually wrong with this apart from the fact that people would feel really weird about it, and maybe be worried that the process picking the vote is unfairly weighted somehow?

I guess the worry would be that this increases variance of outcomes away from popular opinion.
Related is the concept of “Sortition” in which a candidate is just picked at random without voting at all
There are some good arguments for it.
