We should not have to be licensed to do anything! All licenses are, are licenses for government to take more of our money by pretending to do something for our collective good.
We should get rid of all licensing and start handing out "not licensed" certificates to those who do things they don't know how to do properly. (This idea comes from the sequel to Atlas Shrugged called Atlas Snubbed) If every hack who screwed up a system were to get a "not-licensed" certificate and their name and photo were posted in prominent places for all to see, the hacks would either get better or not get any more work.
Licensing just punishes everyone in a lame attempt to regulate those who don't really care whether they are licensed or not.
