I know much more about marketing than crypto technology, so I am not sure if I understood all details of what you wrote, but I feel the direction you point may help.
Either you like it or not, Bitcoin level reached finance mainstream. These people want long term security or, at least and secure clear path to long term security.
The advantage of your post @vazertuche is that it may easily get wider acceptance in a short time, because the main problem is procrastinated, but the same what you propose seems a secure clear path to long term security. I am not in condition to understand if this is real or not, but it seems.
If this is confirmed by peers, it is an important momentary solution to a serious Bitcoin marketing problem, because it shows that Bitcoin is driven in a serious responsible way and so it is worth responsible investment by pension funds and the like.
So I solicit who fully understand it to express if this approach is real, as it is described, or if there are hidden unforeseen traps.
