There’s a lot of unknowns in that and ROI can take very very long time. Not many people can or are willing to take that risk. If that one company is successful then you’ll see that space flooded with new companies.
I remember a story about Oxford. When it was built they planted entire forest of Oak trees so that in 500 years when Oxford will need repairing they have ample amount of wood available. In that age people were capable of thinking 500 years ahead. And we with all our advancement can't even think beyond ROI. Living on other planet should not be seen as choice but something that is necessary.
