Why are there no “perfect drugs” that work well without side effects?

It seems like the more potent a drug/medication is, the more risks are involved with it, where as drugs with very little risk don’t help nearly as much.

We don’t know enough about the human body so we are targeting broadly across many areas.

If we target depression we might target serotonin but serotonin modulates a lot of other functions and we don’t know how to target serotonin in just the brain, most serotonin receptors are in the stomach so a common side effect is nausea.
Now we know after 30+ years of targeting serotonin that serotonin might be just modulating something else and that something is what we should be really targeting.
