"The fact that it is not being done is ipso facto evidence that it would require the consumption of greater resources than the present system,"
I guess I won't start up that small business I was planning. It doesn't exist yet, therefore it must not work.
Where did you get that from? I presume the relevant people are continuously looking at such problems to discern opportunities. Thus far no opportunity has been seen.If you see an opportunity and a profitible way to engage it then go for it. You're not going to do it? That must be perversity on your part. Are you saying that American businessmen are just too stupid to see what is so plain to you? If they are so stupid then just how do you suppose they are going to build a high order system such as you propose?
