Mr Musk.
Kindly buy the studio apartment today and let me know.
Think of it this way.
If I was smart enough to make a deal with you
before releasing that idea few days ago.
(On vertical elevator, rockets launched from orbit)
That i've solved your 100% reusability problem.
And in order for me to release that answer,
you must buy that studio apartment.
You would have whole-heartedly accepted.
+1 billion added from overall.
Still you would have accepted easily.
This is a problem you've been trying to solve for how long mr Musk....
Every moment to R&D, productivity should be saved.
Not squandered.
The loss/damage taken by doing that is more than you'd know.
Timing is everything.
