If you're talking about the Moon landing conspiracy theorists, it doesn't do much harm. Other conspiracy theorists, though can cause harm. For example, the "vaccines cause autism" folks have convinces a lot of people to skip vaccinations for fear of giving their child autism. Enough people are skipping the vaccinations that herd immunity is breaking down and we're seeing outbreaks of disease. These diseases are hurting and even killing people.* So, yes, some conspiracy theorists are harmless but others (especially in large enough numbers) CAN cause harm.
* My son actually has autism (diagnosed Asperger's Syndrome / High Functioning Autism). Even if, despite all the scientific evidence to the contrary, vaccines gave him autism, I'd rather he be autistic and alive than non-autistic and dead of measles/whooping cough/etc.
