Now, *that* is arbitrary. Perpetual check is a defensive resource:
player A only attempts to put player B in perpetual check to force a

in any instance of perpetual check: either player A finds he can't
give check again in some position, so he has to play something else
and probably loses (why else was he trying to force a draw?); or
player B finds he can't play the best response to a check and ends up
losing serious material or getting checkmated. Which of these two
things happens is decided by essentially random-looking things that
happened before the perpetual started.

There is nothing random or arbitrary about a version of chess that
prohibits repetitions, such as Go. As in regular chess, he who
calculates deeper wins.

There isn't a man alive who can analyze to 100 ply.
