If I spent $100 on a Kickstarter, that's a $100 of disposable money not going to a game store.
By that logic,
all "disposable" money is going somewhere other than a game store, which means that they're in competition with absolutely everything. I suppose that's true, but in that regard Kickstarter is no different than anything else, and that makes the issue so broad as to be largely meaningless when talking about why FLGS's don't like Kickstarter specifically.
Hence why I mentioned before that the issue was more germane if you looked at it in terms of different venues for the same products, which is what you pivoted to after that.
Not just RPGs. I'm expecting the Ghostbusters board game any week now, which will be in stores but I backed on Kickstarter, getting a lot of exclusive perks and add-ons in the process. That's business the store is losing:

The lowest tier is the game. Because that's what you're getting. That's 8000 copies of the game not being sold in stores, for cheaper than you could get in stores, and with exclusive options.
This is NOT business that the store is losing, because if this Kickstarter didn't succeed then the game wouldn't be sold in stores anyway, meaning that they'd never have gotten that business for this particular product to begin with. If the alternative to a Kickstarter is that the book, game, etc. is never produced, then that means that brick-and-mortar retailers by definition cannot be losing out, because that product wouldn't be available to be sold by them to begin with.
That's leaving aside the self-evident issue of how, once the Kickstarter closes, you can't order the book via that particular venue anyway. Not to mention that your assertion that "that's 8,000 copies of the game not being sold in stores" is flat-out wrong: the Kickstarter has an option for retailers specifically, meaning that it's going out of its way to include them - so much for the "competition" argument.
And how many gamers now have Reaper's Bones minis completely bypassing gaming stores in the process?
See above. If those dice wouldn't be made otherwise, then they're not taking business away from stores. You can't compete for a product that wouldn't exist otherwise.
I don't think Kickstarter is doing much to stores, but it's not helping. Like online stores, Print on Demand, or publisher stores it's one more way of getting products into the hands of gamers unrelated to brick and mortar stores.
Except we know that this is flat-out not the case. Kickstarter is
nothing like online stores, print-on-demand, or publisher stores. If anything, it's helping brick-and-mortar stores by making sure that the products they sell can continue to be produced with regularity, and that's leaving aside instances of when Kickstarter projects go out of their way to include FLGS's in their project, like the Ghostbusters board game you linked to above.
Well, if you're just making up fictional scenarios in which you assign your own fictional goals and fictional budgets, then sure. If the goal is to buy a puppy and they don't budget enough to buy a puppy, then sure, that's a failure. It's not particularly relevant to the conversation, though.
Neither was your distinction that books that were never intended to go into brick-and-mortar stores and so didn't have a distributor-level print budget weren't a "failure" per se, since that had nothing to do with the topic of whether or not Kickstarter projects compete with FLGS's. One meaningless tangent deserves another.
