Forgetting the global society for one second and just focussing on our individual societies, because we are all from different countries, with different systems of government and different taxation systems.
This is how I see it, please feel free to correct me if I am wrong:
1. Government is a construct of a society seeking to organise itself to be more efficient.
2. Taxation is a construct of government put in place to centralise the funds required to effectively provide services and infrastructure to that society.
Now, no one likes paying taxes, I lose 22% of my salary each month to National Insurance and Income Tax, pay x amount a month for Council Tax, Road Tax, 20% Value Added Tax on anything deemed a luxury and don't even get me started on getting taxed at the pump twice, with Fuel Duty added on top. The coup de grace is having my savings taxed too.
But if we do away with taxation, then who is going to pay for the infrastructure and services?
You expect the world to run on altruism?
I am man enough to admit that freed from the shackles of taxation, you would have a hard time getting me to spend any money on anything except that which benefited me and mine. If everyone did the same, the world we lived in would probably be a worse place to live than it currently is.
Taxation is not perfect, but you can't disagree that as a premise it works.
(I numbered stuff to make it easier for reference)
1. Government is a construct of those with the strongest arms kicking the shyte out of everyone else and getting to power.
2. Taxation was originally meant to finance expenditure and allow for growth, but as I'm sure you know very well the system is badly abused. Though tbh, it's been abused through the millennia.
3. Decentralization & Privatization (the full infrastructure isn't there yet). Most of the things we pay for are private services, if they fail, we go to someone else (phone services for example). The government holds a monopoly on certain services, because holding a monopoly on these services enables them to enforce obedience through punishment (e.g. police, money, etc, can't think of others atm tbh). Competition breeds growth, monopolies breed corruption and staleness.
As an example to your last comment - What public services do you use that can't be privatized? Would you prefer to just pay your taxes to your local council if you KNEW exactly what your council was spending it on AND it was local matters? If everything was fully privatized and you had the option to pick and choose what services/company you and your family needed/wanted, would you prefer that? (I'm assuming you would tbh from what you said).
If government gives up certain things it means loss of power, but growth and more wealth and growth for yourself.
