Right, because that has worked perfectly every time so far...

1. The added cost will simply be passed down to the consumer. Since a perfect alternative doesn't exist and the market isn't free anyways, customers won't switch. And since the number of customers stays the same, profits stay the same, so the producer won't change.

2. The money from the tax won't actually solve the problem. Perfectly usable electronics will still be discarded, landfills will still fill and new devices will still be unnecessarily manufactured. The harm done is the same, only now the government has some extra change.
