Well, there are all the charities related to various diseases so arguably what you're asking for already exists--and is tax deductible to boot. As you suggest, some of these spend a large proportion of their budgets soliciting donations. But those numbers are publicly available. I'm not sure why/how raising funds through a kickstarter would be a fundamentally different dynamic. It still wouldn't really work for individual researchers to use crowdsourcing for a variety of reasons, including the fact that potential funders are really not in the position to judge whether a proposal makes sense or not.
I didn't say start a Kickstarter. That was used as an example of how crowd funding is used to raise a lot of money. Anyway, it was only meant to start the conversation.
You weren't suppose to tell me what was wrong with my straw man but offer a solution that's much better.
Anyway, we aren't going to change the world today so let's end this and just wait until the Elon Musk of medical research appears.
