I see that slightly differently.
I, as a "mere mortal", have already _given_ $200 to Pebble, and $400 to ZPM Espresso.
I got exactly the return I wanted and was entitled to from Pebble, I've had a smart watch on my wrist for ~2 years now and _their_ company has thrived (and they are not under any legal, moral, or even politeness related obligation to offer me anything more except perhaps an opportunity to participate in their next big idea. I certainly don't expect a cut of their eventual acquisition payday).
I got an outcome that, while not my most desirable one, was certainly one of the outcomes I was prepared for from ZPM - a bunch of updates indicating they were working furiously trying ti achieve their dream - and finally a message says "sorry people, didn't work out". And I'm perfectly fine with that too.
I know not everyone views Kickstarter that way (and the "blame" for that falls firmly on both project creators and Kickstarter themselves), but if you expect it to work like a shop - buy your stuff from a shop - they'll ship it with close to 100% certainty, you'll be covered by consumer protection laws and credit card fraud policies and other similar well know remedies. "Kickstarter" even implies in it's name they're not like that. You're often funding pre-manufacturing ideas - along with all the risk associated with the assumptions of getting things finalised and manufactured, and hopefully benefiting by getting your trinket well before the general public and probably at a discounted price for assuming some of that risk.
I've _never_ been "screwed" by Kickstarter - even though I've funded several failed projects. That's part of the Kickstarter game. The same as all those non 1000x exits the VCs fund - they're not getting screwed there, they're playing the risk/reward number game. If they didn't want to get "screwed" by the 99.5% of the companies they invest in failing to return 1000x, they'd be investing in government bonds or blue chip stocks.
You only "get screwed" by a successful (or failed) Kickstarter project/company if you choose to view yourself as a victim (or have a tremendously overactive sense of entitlement).
