Money can and does do all of those things. Through regulatory capture, rent seeking, even just good old hiring goons.
The government itself uses money to do those things. Police don't work for free, prisons aren't built for free, guns aren't free. The government can be thought of as having unfathomable amounts of money. The assets of a country includes the entire country (less anyone with enough money to defend it).
If a sword is kinetic energy, money is potential energy. It is a battery that only needs to be connected to the right place to be devastating. And money can buy you someone who knows the right place.
Governments have power because they have resources (money) not the other way around.
