Drug prices in US go up because of collusion between Insurance Companies and Drug manufacturers. Would I buy expensive health insurance if drugs cost me $100 a month? Most probably never. What if the sticker price for my monthly dose of drugs was $10,000 or $50,000? You bet I'd go get an insurance that'd cost $500 a month. With such sticker shock, manufacturer reaps in profits.

It's great that you're interested in healthcare policy, but you should be careful about making blanket statements without the evidence. Drugs are 9% of healthcare costs[1] and 14% of insurance costs[2]--hardly the decisive factor in your choice of health insurance. And expensive drugs are expensive primarily because it really does cost $1B+ to develop a new drug.[3] Even if you wipe out drug company profits (which we really don't want to do), you'll save at most 3% on your insurance.[4]
Like other types of insurance, cheap health insurance is cheap primarily because it limits your coverage. The biggest impact is that you pay more to see fewer specialists and undergo fewer procedures. It also results in situations in which you're denied a cure for liver disease until you have severe liver damage.[5]
Your solution doesn't solve collusion so much as make a major tradeoff: we can have a world in which drugs cost $1000/year, if we stop researching drugs that cure liver disease. We can have cheap health insurance, if we give up most of the coverage. You probably didn't know you were making that tradeoff, and that's probably not a tradeoff you want to make.
