It is not your money. It is the money that the government allows you to have. You live in a society, and you wouldn't have money without society. We have as much right over that money as you do.
Since money is used as a medium of exchange, it's essentially a placeholder for your labor (when you receive it from your employer/customers as payment) or value provided to others. It is arguable whether society has as much right over an individual's labor as he/she does, I think they don't (while society may have a contribution, it might be significantly below 50%).
One last and minor thing we'll have to disagree on: I don't think government equals society. An individual can be a part of society without being part of government, and I also believe government sometimes represents its own interests at the expense of society.
I know that in an abstract imaginary world you may think something else but that's all it is: imaginary. In the real world, no society = no money = no economics = no government.
Perhaps what you're referring to is legal tender, which indeed requires a government to exist. However, not all money is legal tender (for example, euros are not legal tender in the US, afaik).
Historically, states and credit-based money came first. THEN came the unit of account and medium of exchange money that you are talking about.
Going back to the original point, can you go to a deserted island and make "money"? No. You need society. You need government. You need an economic system. The money is only partially "yours".
Actually, the Wikipedia page on "fiat money" (if that's what you're referring to) says: "Fiat money originated in 11th century China" [1]. There were many commodity currencies before that.

That's if there is only one person on that island. If more people live on the island, they might start trading services and use some some improvised currency, e.g., coconuts or seashells. In this case, you have a society and money, but not necessarily a government.
I'm referring to ledgers of credit. They originated in Mesopotamia, thousands of years ago. Check out the book "Debt" by David Graeber.

See, that's completely untrue. What is actually going to happen is that multiple people on that society are going to bludgeon each other to death once there are enough people to constitute a society.
