Someone here once likened that to not taking someone who has cancer to the hospital because it might make them uncomfortable.
Treating ich is a pain, but you really only have two choices - either treat it, or don't. And treating it means either putting it in a quarantine tank, or killing everything except the fish in your main tank. Anything else is just crossing your fingers and hoping your fish stay strong.
