The point of the law is not to please those who would like to exchange batteries, but to have 90% of the batteries actually recycled, and reduce dependency on raw materials. The government isn't picking winners or losers, it's regulating the waste of scarce raw materials (those present in the battery, and to a lesser degree, those present in the rest of the device). The first company to come up with a battery that lasts 15–20 years will of course have to wait for regulations to adapt, like every other advance in technology in the history of mankind. Your position seems to be that you'd like the government to keep turning a blind eye on companies' wasteful strategies, just in case someone in the future might do something less wasteful.
