The $10k isn't really the point. That's just a number thrown out as an example of what we expect a company to do. The real issue is power. Worst case it'll be either you go into essentially permanant debt by attempting the treatment, try traditional treatments with wildly varying success rates, or probably just die. Money isn't even a question really, it's using cancer and the treatment of it as a way to profit at levels far beyond reasonable.

A business should make money. Has to stay open somehow. Make surviving achievable for a good life and still make millions. We were almost universally in shock when that Bowser fellow has his wages garnished by 30% for the rest of his life. Apart from the legal aspect as a reason, how would this be any different?

This is the world we live in. It shouldn't be though. I lost my Mom to cancer and she's one of those people who would have attempted traditional methods due to the overwhelming cost this one promises. I doubt she's the only one.
