Due to that risk, the wast majority of base research aren't funded by investors. NiH funding for medical research is the single biggest researcher in the world, with a annual research budget of $26.4 billion. All that is paid double by the citizens, first through taxes and then again through insurance/drug cost.

Now imagine if we had a regulation that both forbade universities from issuing patents and limited the price of any drug that is initially based on public funded research.
