Because big pharma will have an impossible time maintaining a monopoly on the production of these substances. They're already produced illegally, imagine the set ups that normal chemists and mushroom growers could achieve if they didn't have to worry about the DEA. Competition is bad for business, so they have a vested interest in lobbying to keep it illegal.

Just in general, if you ever wonder why the US does something the way it does, the answer is money.
