What do you think is being proposed, exactly? Some sort of alternative sun that's going to shine on the entire earth, that we'll all be forced to look at?
No. I used a rhetorical device to highlight a theoretical monopoly we assume would never exist. But imagine I launch a space sail that can cast a shadow on any part of earth I chose. I could block or unblock sunlight at will and grant access only for paying customers.
Is that something that should be permitted?
