Surely needing a special screwdriver won't stop someone who wants to set up a shop, at least in a first world country. It's going to be far more effective at stopping individuals from doing home repairs. The reason is the shop buys screwdrivers then uses them over and over so the price-per-use isn't very high, while the individual would buy them to use only once or twice so the price-per-use is higher.
