Except that designers then tread in fear of violating patents and produce much cut down versions, harming the consumer.
I once worked in a place that designed a CPAP pump, which is essentially an air pump with a humidifier. It has a removable water tank with a heating plate for humidifying the air. We had to use a removable plate to expose the tank instead of a door - because our main competitor had patented a hinged flap to access the water tank!
Regardless of how obvious prior art is, it's cheaper to make minor design changes than to spend years in litigation. Even though it's worse for the consumer, you have to avoid anything patented unless you have the ready cash that Apple has lying around.
