You could only do small parts of this, and only if you were fabulously wealthy. Lab equipment is very expensive - always in the thousands, often in the hundreds of thousands and sometimes in the millions per piece of equipment. Certainly you won't publish anything without the equipment needed to do experiments. And a lot of things like chemicals are restricted for academic use only (for obvious reasons...), you can't just walk in to walmart and buy a tub of acid or radioisotope. It's also pretty freaking dangerous to be playing around with chemicals (if that's the direction you take) or really a lot of lab equipment without having the proper training and understanding of how it works.
I don't understand why you're so against being a real scientist. You'll accomplish far more to increase scientific knowledge that way than you will be cooking things together in your backyard without any scientific background....
Also, your ideas about generating income are insane. You think people will give you money for publishing articles and speaking at conferences? As far as I know, they don't even give real speakers (not only with phd, but with a history of high quality research) money for those things, other than travelling costs. You would never be invited to give a talk at a real conference without a masters and probably a phd, let alone without any scientific training at all. Conferences cost hundreds to attend, unless your costs are covered. I can't imagine them paying a speaker. There might even be laws aganist it for all I know. (disclaimer: could be different in the states?)
tldr - your idea is a pipe dream and not even close to possible in the way you imagine. The closest thing to it would be getting tenure at some low level university that doesn't care that much what you actually study.
