You wanna be your own practologist, banker and brain surgeon, you go right ahead.
Something tells me you did try your hand at self-brainsurgeoning, and it worked out ...well, let's just say you tried

Seriously tho, I don't want to be my own ditch digger, bankster or ass surgeon, for basically the same set of reasons: I'd rather pay someone else to do it, someone who's good at it.

That's the way society works, beecoin: I need my horse shod, I don't become my own blacksmith, I go to the village blacksmith, who's a wiz at it, because gets lots of practice.
Smithy, tho, he sucks at electronics. So when he needs some weird gear built, he comes to me. And then there's a baker, who backes better bread than me, and an ass doctor, who ...does whatever it is he does, etc., etc. Society! Learn how it works.

Oh, BTW, banksters are not teh gubermint. You nutters like to bitched about that.
