I just think agreeing to let any individual in all cases, legally, be able to give money to another individual for research, is maybe jumping the gun a bit. Ok perhaps you don't agree with my idea of wealth inequality, fair enough, but if for example you are trying to fund WMD research, or research into pseudoscience, or research that is inherently biased, I would actually like to see that banned I'm afraid. Other workarounds maybe include banning the research area itself, or banning newspapers from publishing it, whatever.
