Great, I honestly think that's awesome, but I meant it as more of an illustrative example that we all have cultural biases and we shouldn't be so quick to label others' practices as "dumb" just because we don't understand them or practice them ourselves. If it was actively harming anyone then that would be another ethical rabbit-hole, but it's not as far as I can tell, and it's their money to spend/waste as they please.

Now if we're talking about illegal eruvs (eruvim) such as steel cables or chains at ground-level that have killed motorcyclists in the past...I obviously think that's a good thing...
