Where I live, dogs do not need a license to be a dog. But they do inside of Columbia and in many, many cities across this great country and even world of ours. When I am President, dogs and even cats will no longer need a license to exist.
Humans have come up with the concept of licenses as yet another ploy to trick other humans into paying taxes.
Taxes are stupid. The government of the humans keeps creating more and more taxes to pay for more and more stupid things. The human government creates departments and bureaus to create taxes and then use tax dollars to pay for those departments and bureaus.
I have heard from my Human that the human government actually dictates what type of posters are required to be on the walls of businesses. I asked my Human who reads these posters. She said that no one does, other than her corporate auditors who visit occasionally to check on things.
One of my favorite human government programs is the so-called "Paperwork Reduction Act." My Human said that in the course of her job, she will get a multipaged document from the human government with one sheet of paper inserted with the something like the following printed on it:
Hey Humans! Look at us! We are telling you on this sheet of paper that the government really, really cares about you. Because we are caring, we are have calculated that it should take you 30 minutes to read everything on this form and only 15 minutes to fill it out. YMMV.
