That's exactly the idea and a great idea for that matter so that bitcoin will become widespread. Unfortunately, there are some reasons why this is hard to do. Those who own companies are governed by laws and regulations and bitcoin is not so it would be very hard to incorporate it with their policy. Also, understanding the whole payment process of bitcoin is quite a challenge so many of them don't really want to get into that kind of trouble.
rather, the main problem is that States understand a small amount of bitcoins and there are many in someone's hands that they do not know. therefore, they will try to find a new coin as a common compromise for governments.
