And then we go, "oh gee, we don't have enough people to audit white collar crimes because the Small Government crusaders gutted the IRA, for some reason".
It's not about small government, it's about an ineffective, castrated government, so companies like Exxon can steamroll it and have their own way to profit.
Exxon would love nothing more than this... small government.
Smart!
Once you accept that you have to give a 3rd party the monopoly on violence you are now effectively giving them the authority to do as they please. You can wax on about how government should have less power on internet forums, but organizations with power and weapons don't give up that power without using the weapons.
Perfect justice is impossible to achieve (someone will always be able to bribe someone else), but by spreading out the corruptible people and by putting them in competition on a market (where reputation matters), you will get a fairer system than the disgusting monopoly we have right now.
