You're right that you're unable to answer it through Scripture or theological explanations because the Bible doesn't tell us (though I disagree with Piper that this is the most difficult question).
> God created Lucifer as the greatest of his heavenly hosts.
First of all, we don't know this. This understanding comes from a tradition, and now considered false, reading of Isaiah 11. It is now widely thought, though many Christians and deconverted still hang onto the tradition they were taught as children, that this text is about the king of Babylon, not about Satan. The truth is, we are told nothing about Satan's origins. We don't know what kind of being he was or what happened to him.
> Lucifer betrayed God by committing a sinful act; idolatry (of himself).
This also comes from Isaiah 11, which, it turns out, is not about Satan.
What we do know is that God created all things good (Genesis 1), and that God can create only good things (James 1.17). So we have to surmise that whatever act Satan took to disassociate from God, it was an act he took in and of himself as an exercise of his will. (Jude 6 verifies for us that spirit beings have will.) That's about all we know, and that is even by inference, not by what is written. There is nothing written about the origin of Satan.
Here's what I guess: God created all things good, but since God is, by definition uncreated, anything He created (which is all things) is less than God, less than perfect, less than eternal, less than...oh, everything, which means all created beings are vulnerable to and capable of missing the mark. Satan, whatever he was, made a choice somewhere along the way, as was his right to do, and disassociated from God. How a being could see the beauty, majesty, and power of God and turn away is beyond me, but hey, it obviously happened. How, and why, we are not told.
> Isn't a sin inclination (inherent sin) in Lucifer a sign of imperfection in God's creation?
It's not a sign of imperfection, but is necessary by the action. Any created thing can't qualify as uncreated. Anything that has a beginning can't qualify as eternal. It's not a flaw in the Creator or in what He created, but endemic to the act. If I were to create the most perfect cut crystal glass, I'm not to blame if someone drops it and it breaks. Glass, by nature, breaks. That doesn't mean I didn't create it perfectly well.
