I'm looking at recirculating the chilling water through a handy cistern, but that project hasn't matured yet, as I'm starting to think about how to put the cistern back to its original use in the broader context of water use in the household. (I'm just providing an answer to what you mentioned, not really sure how this pertains to the RO issue.)
4. I'm not sure I can agree from the information you've provided that anyone (= me, presumably) can keep waste "minimal" by just being "creative." I keep it as minimal as is reasonable, and reasonable means minimizing the load on our well.
I suppose using a well is different than the pressure a normal water system supllies. My comment was pointing out that the volume of water wasted can be managed. That was your original point.
I only brought up chilling on the topic of waste, so it almost certainly uses more water than the waste of RO. Ice came up to point out that lots of brewing is water and energy intensive.
That said, I would wager most homebrewers use less total energy than shipping bottles cross country.
