Even if these worked for everyone, which they don't, then a cure which blocks the main male sex hormone whilst messing drastically with your blood pressure is not a solution.
If it works for someone then great youve partially solved one problem, but not a solution were all looking for.
OP you are pretty much right, as long as you don't have Norwood 7 DUPA and can tolerate finasteride, with the best FUE surgeons in the world you no longer have to worry about hair.
