I disagree. These are problems everything experiences. Having immediate feedback to a potential solution helps immensely in determining its effectiveness. As instrumentation and analytical methods improve it is entirely reasonable to expect people to create their own treatments that are effective.

Right now most of the necessary equipment is siloed in research institutions and hospitals.

It seems medical quackery gets a disproportionate platform, I think in an attempt to educate people about how dangerous it can be. But go look online or even in a brick and mortar store: there's plenty of stuff designed to take your money that won't improve your life.
