I think you and I disagree about the necessity of government.
I think anarchy is antithetical to human nature. We are ordered creatures, so we need an ordered society. This implies some sort of hierarchy and authority.
The one we currently have ain't it, though.
No king but Christ. I don't need another human being to tell me what the heck to do. I do not intentionally harm others. I do not intentionally take other people's stuff without consent and offered compensation.
WTF do I need government for?
How do you handle these verses then ? 
To steel-man nostr:npub1q6ya7kz84rfnw6yjmg5kyttuplwpauv43a9ug3cajztx4g0v48eqhtt3sh's position, those verses speak of how we ought to comport ourselves towards the authorities under which we found ourselves in the circumstances of life. They don't treat directly only whether or not those authorities ought to exist by natural right.
So the governments of the world are not ordained by god ?
Uh, no.
Also, why did Jesus advise his disciples to sell their cloak to buy a sword if they would supposed to blindly submit to an evil "government?"
A more modern way that I prefer to put it:
Resistance to tyrants is obedience to God.
Governments are ordained at least by God's permissive will. If the government is unjust or tyrannical, then I think there is a moral obligation to seek change for the sake of justice. We ought to give some amount of deference to authority that is generally just, however. How that plays out "on the ground" is complex.
The link below was just a cursory search regarding exegeting the verse you brought up. My question still stands- how do you handle those verses in Romans?

Also if you believe governments are not ordained by god, how do you handle this verse in Daniel? 
Our nature is hierarchical. God is in Himself a community of persons, but also a hierarchy. The Son proceeds from the Father, and the Holy Spirit proceeds from the Father and the Son.
Within ourselves, we are created in God's image, and thus there is a hierarchy within our own souls. The intellect rules over the will, and both govern the passions.
Families, likewise, are in the image of the Trinity. A man leads his wife, and both parents together raise and govern their children.
To deny hierarchy is to deny our nature. We can discuss at length what kind of human hierarchy is just, but it is the error of liberalism to assume that hierarchy is not necessary.
I have no need to submit to any man, with the possible exception of one whom I take as a Shephard. But guess what? God shepherds are few and far between, so, again: no effing thanks.
True that some people have matured enough to manage their lives on their own. To them, government is but a cancerous organ, feeding on their livelihood and making them sick. But not everyone has made it to this level. In fact, over 90% of people all over the world are still living in the shadow of their government without knowing what sunshine even is. So, yes, I think government remains the necessary evil by which an immature society survives its own harm, till finally, enough people wake up and rise to see the dawn.🌸
What is the standard of maturity at which a person doesn't need government? Who determines that standard? How are the rest of us to know that someone is capable of acting as their own authority in all earthly affairs without endangering the rights or livelihood of others?
needs AI as a government, humans cannot be trusted
Who programs the AI? How do we know that it has the correct values to govern us by?
Of course, it’s not the current AI, it’s the autonomous AI of the future. No human being has authority.

Saying "oh some future AI will solve it" doesn't answer those fundamental questions about why we should trust an AI government over anything else. You're declaring some perfect AI by fiat without addressing the actual problems with the proposal.
There are no necessary evils. None. Period.
