I always thought waxing is most suitable for weekend warriors. You only ride in good weather. If it is raining, you stay home. You like your stuff looking shiney because cycling is nothing but a lifestyle hobby in your eyes. Perfect case for wax.
Commuting, maybe if you use two bikes, a waxed bike for nice days and an oiled bike for wet days.
Touring, hard no to wax.
Where have you gotten that strange notion?
+95% of the riding that goes on in my household is all weather commuting or utility riding year round. I maintain all the bikes we have, and since I like to make life easy for myself, all of them have waxed chains. Having tried pretty much all the other alternatives from cheap to expensive to diy, hot wax won out with reduced maintenance time, ease of use and increased longevity of components. Cleanliness is a also really nice with small children.
I knew I should have taken a picture from my last commute! I had my rear mech caked in a pound of slush and the cassette was nearly completely covered by it when I got home. It was a miracle I could change gears in the first place. For these kinds of conditions wax works best especially when the slush has salt in it.
Waxed our chains on our last tour too. It worked fine. Could be better but that's solved (aha..!) by either a solvent based wax or heating the chain. For non-flight tours the solvent wax will probably be the best option.
