I guess. But commuting may be the bulk of all bicycling I do. To do most of my bicycling on a crap bike would be very disappointing.
I could also eat sawdust at work for lunch every day, if sawdust was nutritious. I don't need to eat tasty food. Nor wear comfortable clothes that fit - sackcloth will do.
I'm happy to ride a really good bike. I want to be happy more often.
