Many customers would rather not multihome directly, and prefer "set it and forget it" connectivity. It's much easier to maintain a multi-pipe connection that consists of one static default route than a pipe to multiple carriers. The former requires simple physical pipe management, which can be left alone for 99% of the time. The latter requires BGP feed, an ASN, and typically much more than 1% of an employee's time to keep running smoothly.
Hrm, people keep saying that BGP is hard and takes time. As well as my end-user-facing network responsibilities, I also have corporate network responsibilities here. All of our corporate hub locations are multi-homed (or soon will be)... and I honestly can't remember the last time I made any changes (besides IOS upgrades) to BGP configs for the 2 hubs in the US. (We're moving physical locations in the "international" hubs and taking new providers, so I'm discounting those changes as you'd have similar changes in a single homed statically routed move). If you don't have multihoming requirements other than availability then it really can be fire and forget.
