1. Mandate that every mass produced device with a li-ion battery have a simple mechanism to remove the battery

How do you propose to mandate this?

[WalterSear]

You make the sale of non-replaceable battery devices too onerous in California.

Create a law that says that if the battery is not user replaceable then the manufacturer must replace it for free when its charge capacity drops below 90% of its original capacity.

That would shift the market pretty quickly towards user replaceable batteries.
