No one is "preventing" potential medications or interventions from being developed. Many promising discoveries are just not beneficial enough for the society as a whole to justify allocation of funds for development, or if developed, justify expending public resources for treatment. Whenever the whims of the ignorant mob is not sated, whether be it healthcare, addictive substances, social regulation, the over-emotional whine about global, evil conspiracy of reptilian aliens.
Without the sociopolitical stability provided by the "parasitic" 'gubermint, men will not be living in prosperity to investigate technical and scientific knowledge. Without the so-called "overlords," man would not even be literate, as the preservation of written record and propagation of literacy was sponsored by kings and emperors throughout history. Without religious institutions and legal bureaucracy, social norms and morals would not have been ingrained in the ignorant rabble for civilised society to function. The current luxuries that we enjoy have been sown by our betters in the past. Rather than feeling gratitude for our borrowed lives, you incite ingratitude and arrogance.
