Well you hit the nail on the proverbial head. The compact will handle 99% of people's use-cases, the truck will handle 100%. People don't want the hassle of renting something or paying for help for the 1% of cases their compact wouldn't handle.

Believe it or not, I'm with you; I live somewhere where it's sunny all year round, so I get around with a motorcycle as my primary transportation year-round and evangelize them as the cheap alternative to people struggling with car-related payments. But no, my motorcycle isn't going to carry a 2x4. Someone who cares about supporting that, even if they only need to do so exceptionally rarely, is gonna buy a truck. And then they won't have the money to buy a motorcycle on the side.
