By all means!  After all, the continued and expanded profits of the sickness industry depends on more sickness and expensive licensed medical products which lead to more sickness.  No way that can happen if less expensive unlicensed products are allowed which don't create more illness and might even (gasp) heal people where they had no need of further medication.

It's really quite simple - the economic health of the sickness industry is inversely proportional to the physical health of the consumers.
