No need to legislate this. Most people I know go out of their way to avoid buying products that don't charge with a USB connector if they can avoid it - at least computer-related products.
Me, the last device I bought with a special charger was a Casio Exilim camera that has unique enough features that I had no other choice. But I hate that charger each time I have to carry it with me on business trips when I already carry a USB charger that takes care of all my other devices.
