The only other forms of wealth are matter, which is even more limited than energy, and information, which is theoretically infinite but practically requires matter and/or energy to be stored and/or processed.
Can you give an example of a form of wealth that's infinite in amount?
Even if we built a Dyson sphere, we would not be creating wealth, we would just be making available to ourselves more of the wealth that's already out there.
