If you work for the State you are not “serving”.
If your “job” comes with a paycheck extorted from people who didn’t value your effort enough to pay for it voluntarily, you are not serving.
You don’t “serve” in the military, in congress, or “on the bench”. You prey on people’s life, liberty, and property, but you don’t “serve” anyone beyond the political bullies who hold your leash and steal money on your behalf.
If you really wish to serve, provide a service which people will be willing to pay you for. One which they won’t have to force their neighbors to chip in for. Be a good guy like Ross Ulbricht, not a bad guy like Donald Trump or Barack Obama.
