This has been done (somewhat) to date. However, it is not a long term solution to the reality of the needs when we get to the stage that millions of transactions are being done every second (even well before that stage).
There is plenty of HIVE being printed daily for it to be utilized for many things.
Unfortunately, we all tend to be somewhat affected by the fiat world we live in and as such seem to apply that approach or thought pattern when considering the future of crypto.
Hey, I am being very self critical when I say that.
However, lets start thinking more "long term". The DHF is not there for "infrastructure", nor was it ever intended for that. It is an answer to a decentralized means of stimulating the overall growth and diversification along with out right international utilization of Hive, HIVE and HBD.
One way that helps me get out of the totalitarian fiat frame of mind and get into the heart and soul of the crypto frame of mind is to look at the figures being printed and to simply ignore any fiat values.
When I do that, I see that millions of HIVE are being printed monthly, it is more than plenty HIVE to be utilized in a defined, hard coded manner which ensures our chain can accommodate to ALL the financial needs of all 5 BILLION people on the internet (and maybe even those who do not hang out much on the internet).
