Here's the thing; that (a completely transactional relationship between all elements of a team) doesn't actually work well to make good products. Sure, a bunch of companies would probably do it as it's easier to measure worker production that way, but async also requires a different type of management and admin work that has to change as well. A lot of current managers won't be able to hack it, frankly, without the measured 'butts in seats' element.
Personally, I think it should be coupled with an investment in HR to get more qualified and motivated people working on the problem. It's a different concept for business and teams, that's all. Applying the older paradigm is going to be a problem and while a lot of companies will do just that they will also be less successful overall.
