I don't understand the concept that if I have a loaf of bread, that I worked all day for...
I may be able to help there...
Money isn't something tangible, like bread. Money is a game token. It's like D&D hit points. It has value in the context of game, because other players are playing by the same rules. My dwarven cleric has 43 hit points, and my American corporation has three million dollars. Same principle.
If you just bake a loaf of bread, nobody cares. But if you convert your bread into game tokens, then other players will expect you to play by the game rules. If the local game rules include a tax on your tokens, and you hide tokens under the table, then the other players might accuse you of cheating.
Now, I'm not saying our local game rules are perfect. Maybe they'd benefit from a revision. But if you start thinking of money as something real, rather than as a game token, you're going to get confused. You're speaking in terms of "stealing," when you should be speaking in terms of revising rules to improve the game.
On the separate question of whether our game rules should include tax, I'm not an expert. But I found a list on of countries by taxes as a percentage of gdp. https://en.wikipedia.org/wiki/...
For the most part, countries on top half of the list seem like nicer places than countries on the bottom half. There are exceptions, but overall it's hard to deny the trend. So I'm not sure lower taxes actually lead to a better-functioning game system.
Right now, I pay a lot of taxes. If I moved to Hati or Guatemala, house rules would allow me to accumulate tokens faster. But I'd rather stay here. Our local rules seem to make fo a better game, despite the annual drain on my tokens.
