I don’t know if I fully understood your question and I don’t know if I’m that conservative either but I can give it a try.
First the sermon on mouth. To make it simple, it says what it says. You cannot have two masters. If you serving money, you are not serving God. This doesn’t mean you should not have money or wealth.
1. Thimothy says: “If anyone does not take care of his own relatives, especially his immediate family, he has denied the faith and is worse than an unbeliever.” Now, how can you do this without money?
So, money is good but we should remember that money is meant to be used. “He died for all people, so that those who live should no longer live for themselves but for the one who died and rose for them.” If someone thinks that he/she can come to Christ and leave wallet home, he/she is fooling his/her self.
“Judge a tree by the fruit that it bears” has not much to do with government. It is directed against those who look, smell and try to behave like christians, but they are not. So the fruit that you are looking for might be, for example general behavior. Is the person loving/friendly or quarrelsome. Is he/she doing his/her best to help neighbor or is he/she standing on roadside with a sign “God hates fags”. How person uses money is not very good “fruit” because there is no way to know how much someone makes money and how much is then spended unselfish. And even if we know, it might not be our business...
Then the place on Acts you pointed. “Peter asked, “Ananias, why has Satan filled your heart so that you should lie to the Holy Spirit and keep back some of the money you got for the land? As long as it remained unsold, wasn't it your own? And after it was sold, wasn't the money at your disposal? So how could you have conceived such a thing in your heart? You did not lie to men but to God!”
Ananias was not accused on hoarding wealth. He was accused on lying to God. He had right to keep his farm or some, or even all of the money he got from it. Instead he tried to display himself to church as something else that what he was and got killed by God for that.
So why were believers selling their farms and houses and sharing the money they got? They were expecting that Christ will come back in few weeks. Or maybe after a couple of years. They were not expecting they have to wait over 2000 years (or more). So they wanted to use all their properties to make the Gospel reach the other side of the world before Christ comes back. And as we can see on the Bible later, they got in to smallish financial crisis because of that and then churches in area that we today know as Turkey had to collect extra offering to help them out. So everything you read from the Bible is not meant to be understood as example of good life.
I hope I understood your question right and I could answer somehow.
Edit. It seems I partly missed your question. There’s not really much I can say about other counties taxing systems. But Bible tells christians to share their wealth to others and for Gods Kingdom. There’s no question about that. However Bible does not support the idea of forcing someone share ones wealth to others.
Only place I can now think of where Jesus talks about taxes, he says "So give back to Caesar what is Caesar's, and to God what is God's." That could be understood (and how I have understood it) so that christians should pay all the taxes government expects them to pay. And if there are enough christians in government, they can set taxes as high or as low they want. That’s how democracy works.
