I'm not sure how much clearer TSLA can be. They do not need any more capital than they already have in order to execute delivery of Model 3, and Model 3 program has been designed such that the more of them they sell, the faster they gain capital. Once Model 3 is shipping, the days of needing capital raises are over.
SCTY acquisition brings no additional execution risk, and actually de-risks it by providing working capital now, AND offering the option to trade the future cashflows for cash now any time they feel like they 'need' capital but the markets aren't favourable. They said no cap raise in 4Q16, and probably not one in 1Q17 or 2Q17 either.
I mean, we can agree to disagree, but your hypothesis seems to be that they're straight up lying to investors.
EDIT: and the profit *is* already flooding in. 29.4% GM on TA alone.
TSLA's mission statement simply does not allow them to delay Model 3 long enough that they could execute it by waiting for S/X to generate enough profit on their own.
