If everyone was to use Kickstarter in this way, Kickstarter would lose the appeal it has for hosting niche / innovative projects. Diminishes the tool for the rest of us.
I back a shitload of kickstarter projects that are basically 'help me collect enough preorders to get a print run', and I'd much rather kickstarter be a hub for that kind of thing than another bottle opener / wallet / watch design.
That's why she needs a kickstarter.
It's a marketing tool, possibly moreso than it's a crowdfunding tool.
