hmmmm
well firstly i would abolish silly protocols and i don't wanna make a list but there are a LOT of things i'd like to change about the one im currently in -_-.
Hell, I'd build it up to be a reasearch capital and a refuge for genetisicists, and then when we have developed disease free livestock i'd patent them sell non breeding pairs and rack up cash enough to have offshore manufacturing plants, remove cars; instead use a rolling road powered by a atomic power pile for the entire city, and then i would use tax money to found companies for games design & agmented reality. Oh and Then i would use the capital from the companies i founded to make a new infrastucture project; The Space Elivator. Once my country had a Strangle hold on the buisness of what goes up cheaply into space (THe elivators require near 0 to function as it's mostly counterweights) I would make sure that each month a pack of supplies is pushed over towards mars so when people actually manage to get there i will claim it is a protectorate of my country, and demand they pay for using my equipment. Unfortunately the moon is already taken and well screw venus. so my little slice of world would take everywhere by the throat. It would be awsome, of course It would be manditory for each student to complete some kind of momentus project before they were allowed to finish school with honours. Anything as long as it's impressive. Games would be used for education, and the sceince of inducing the creation of patterns in nearual tissues would be advanced to the point that school would be obsolete and people would gain skills through the use of stimulation to effectively simulate the memories that are condusive to skills. this nation would be known as positivana. I Wish It Existed.
The technology created in the country would be subject to a fifty percent goverment markdown so that gaming tech would be cheap as chips and you could buy entire VR rig for around 500 dollars. There would be a goverment created game which uses face mounted displaies to overlay scenes over what you see. For example a adventure game might cause you to be attacked by ninja bunny pirates on the way to the shops and have to fen them off with the weapons now sprounting from your arms.
Most of the tech for this to happen is around but it isn't cheap and people don't care enough to use it. Also if you really had to have a car then it would use ceramic hydrogen fuel cells and the body work world be interchangable.
.... theres a Hell'va lot more i'd do but that's the basic stuff
