I remember when i first started using GIMP the thing that threw me the most was that there was no 'safe default' state that you could get to by pressing escape, like 'select' is for other programs.
If you think this is a small thing consider that escape/back is one of the only 3 default controls on phone UIs. It's super important and Gimp doesn't have it.
Your point is not very coherent, I'm struggling to understand you due to how much you've written and the lack of formatting.
Some brief things to pick out:
Corruption is not just a socialist thing it's everywhere. India has huge corruption problems and is capitalist.
Taxes are not 'accepted feudalism' they are the basis of communal living. Even anarcho-capitalists recognise the need for roads and farming subsidies.
You're right that good can be done in any system but the idea of all of this is to find a system that encourages good and discourages greed. If we could rely only on everyone just deciding to be good there would be no need for any politics. You'll notice this has never happened in millions of years of human existence.
