I don't think that even Rh(null) blood, unicorn tears or HP color ink liquids are commercially viable to launch at prices around 10-50k$ per liter. And that if that whole assembly will work at all at prices they are advertising today (1/20 of comparable commercial rockets, but it will have very small payload).

PS: I don't have numbers, but I'm guessing that F9 hitchhike Transporter missions cost less per kilogram, compared to the imaginary numbers for non-existing full scale Spinlauch.
