All my riding is on rough, poor roads with a good amount commuting in winter and I don't see what the advantage of larger wheels are. They just make those wide tires I need heavier.

Dirt/off road sure (there are many strange contraptions which are useful in the wilderness), but it's very hard to see any useful purpose in such riding for the 99% of mankind that lives in civilization, hence, larger diameter wheels are pointless. You can't say the same in reverse because small wheels have many advantages while large wheels have only one esoteric advantage at the fringe of a bicycle's capability. If riding off/unpaved road had a point then the bicycle would have been invented shortly after the wheel instead of thousands of years later during the rise of modern civilization.

Large wheels are only have advantage for sport; in other words diversion; in other words pointless.
