OMG. This guy conflates ideas with actual products and apparently believes the mobs who attacked John Kay would have respected patent laws! John Kay didn't just have an idea he took action to build and promote it. He was mugged by people who didn't believe in property rights which have nothing to do with government initiating force through patent laws. Like tariffs, patent laws erect barriers to competition protecting the less able businessmen and preventing more able businessmen from serving the consumer. This retards innovation and hurts consumers.
