TSLA, SCTY and SpaceX business models just can not work because at the end of the day, a business must make some profits to sustain. Growth is good, but without profits, sooner or later creditors will come knock at the door, and when one creditor wants their money, other creditors will follow suit.
Both SCTY and TSLA lose money on every sale. When cash runs low, all they do is to issue more shares.
