There are plenty of arguments we could all make about what we do or don’t agree about the Bible, contemporary Christianity, etc. But we can’t control a single aspect of it. What you’re looking for is control over every facet of your life and everything you don’t like about the world. You already know that kind of control doesn’t exist for people. And that appears to be what frustrates you.
There is a time to born and a time to die and they are not both at the same time. They are both exclusive of one another and happens in their own time.
A very important statement of Jesus was that we must have the ability to discern things, not just the weather but also the signs of the time. And that time for discerning is now, else how could we know good from evil. In fact the lack of discerning allows one to call "good" evil and "evil" good.
The bible is a living moving book, it is the book of life and not a static dead book that applies to the dead, that is, those who live in this end time period. Jesus also told those who would follow him, " Let the dead bury the dead"
So to the premise of your above statement - "What you’re looking for is control over every facet of your life", we have to understand that knowledge is key and as Hosea 4:6 states you will perish for lack of knowledge.
The bible does state not to accuse dignities, even Satan, because it is God who determines their actions etc. That is a given, they have been put to rule over us and only God has control over them and not us.
But Paul when talking about the brethren (and also John) tells us not to have anything to do with those who claim to be one of us and who at the same time refuse and reject the authority of God. (In other words they are worse than the ignorant or even those who are deceived or misled by others.)
2Co_6:15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
1Ti_5:8 But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel. (We are expected to support and feed the flock and if we are breaking down, even when we lay claim to Christ we are worse than an infidel)
Therefore the final statement for our days here in the book of Revelation is to come out of them. (Paul says the exact same thing in Corinthians) else you will inherit the plagues that is about to come upon them.
Knowledge is key. Hosea 4:6 states - My people are destroyed for lack of knowledge.
Finally, as you said about the Gnostics, truly the Spirit transcends everything and the flesh profiteth nothing, therefore only those who have come into that truth (not just understanding it academically) but in spirit and in truth will truly be free.
