I think the inexpensiveness of our various locales may actually be causational. A quick survey of the people I'd consider bootstrapping peers is a wheres-where of "Places You Wouldn't Expect To See A Tech Company." Almost all of them are relatively low cost-of-living.
In my own experience in Gifu, the fact that ~$3k a month not only supported me but paid roughly market wages was enormously helpful. Had I started in SF or NYC or Tokyo, the need to have $120k a year in profit to have the same standard of living would have probably kept me tied to a desk at AmaGooBookSoft forever. (I can afford to live here in Tokyo these days, but man, $3k in rent is an awful lot of bingo cards.)
