Identifying homeopathy as a case where less freedom would benefit someone is not sufficient to argue that it's a better policy.
Everyone who laughs so confidently at homeopathy, would likely do the same for a cutting edge treatment, which has yet to be widely recognized as effective. And in that case a lack of freedom would lead to a worse outcome.
That's complete hogwash. Homeopathy's core idea is that you can magically negate a poison by diluting it billions or trillions of times into a cure usually to the point where there's no detectable component anyway.
Experimental treatments definitely invite skepticism, and should. Humans can generally contain more than one level of skepticism - this treatment has a certain rate of failure, this treatment is unproven, and important, this treatment has no mechanism that could work and is a scam meant to separate a fool from his money.
