So is the lighting network imperfect? If it is, we shouldn't pollute bitcoin's perfection.. maybe it's not the solution

Nothing is perfect.
You're right, bitcoin seems to have 1 sole imperfection, that is the scalability problem. Or, it appears to be a problem.
Let's say that bitcoin is the closest thing to perfect that humans have ever been able to come up with. Also, isn't it the only human-made thing with the potential to last forever?
