support authorities" to mean unconditional support of oppressive regimes that trample on the rights of its citizens. By "authority" it meant good & just government.

Yes, indeed. Think about paying your taxes too. Lots of statists claim that Yeshua said to pay your taxes and for that reason gove your support to a state (corporation).

What they fail to mention is that he only claimed that Caesar's face was on the coin. So it is his! So give back to Caesar's what is his!!!

That doesn't mean:

And also pay your taxes and give unconditional support to Ceasar as your God and idolize the state and everything it stands for.

It means give back to Ceasar what is his and walk in faith with nothigg but a walking stick. To help those in need and above all listen to God and do the works of Yeshua.

Francis of Assisi started his own brotherhood for it was to live a utilitarian life and live above all in faith.

Money, especially blood money based on debt should be renounced. How? To live in faith and preach the way of Yeshua. Do as he did. If an entire brotherhood lived like this and followed Yeshua, money wouldn't be needed.
