John of Patmos would like a word with you:

And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass.

• Revelation 21:21, KJV

Here’s the full chapter for context. There may be some room for arguing whether the “new Jerusalem” is Heaven. But since it’s pretty clear that God lives there, I think it fulfills the same general purpose.

He got an entire art supply empire with franchises that sold painting courses (and maybe still do?).

I think he also got screwed out of most of the proceeds and possibly even the use of his own name because he had a shady business partner.
