Not for building redditstructures like ringworlds. Note, I said:
>magic material used to make ringworlds
Because only a magical material can create ringworlds. Larry Nivens had to come up with a made up material called scrith in order to make it work. It would need to have the tensile strength of a nuclear force. Even then, Niven's whole series highlight faults and problems that make the whole thing sound much more fragile than a simple planet. A single small meteor could destroy it all.
