I've wondered if insurance should even cover drugs that are needed on a regular basis

I'm not talking about not covering drugs for short term illnesses, but the long term stuff like blood pressure, psychiatric, etc

The reason being it's not really insuring anything because it's always needed

If people had to pay for it directly then prices would have to come down to what people can actually pay instead of what the insurance company will pay

I could be totally wrong and misguided though
