Yeah, but who were you asking? You seem to have someone specific in mind since your last post is made in the second person (e.g. you refer to "you").
For what it's worth, I think that hypotheticals aren't worth very much in a discussion, since they're typically posited to set up some ludicrous example that's extremely unlikely, which I'm guessing is why your question was ignored. That said, the question doesn't make much sense. What would happen to retail outlets if literally all new products were funded via Kickstarter? The answer is nothing, since after they were funded the books would still need to be sold to everyone who wasn't a backer (or was a backer that didn't get that reward). The retailers are still needed just as much as they are otherwise.
Please cite the percentage of successful kickstsater campaigns which sell their products at FLGSs. (In any time period which is at least one month)
