And when the phone is 4 years old and won't make a full day without a second charge (as opposed to just overnight) then you'll probably simply replace it despite it being good for another 4 years, easily, if it had a new battery. That may be fine for you, but not all of us are so filthy rich.
"What's with the US government mandating seat belts in foreign cars sold here!!! How dare they! Instead of requiring seat belts, the US government should offer tax breaks to auto makers who do offer seat belts. Surely that's the right way to incentivize them."
"What's with the US's 'Tylenol bill' that requires tamper proof cases on over the counter medications to prevent another cyanide murder case like the one in 1982? How dare the US government interfere in the design of drug makers' product packaging. Instead of enforcement, they should have just given a big fat tax break any of over the counter medication producers that voluntarily decided to offer tamper proof containers. That would surely be in the public's best interest, right?"
Your arguments are weak, my friend. Do better.
