First of all: Regardless of construction materials (or where you get them), a Dyson Sphere would be useless because GRAVITY is impossible on the inner surface of a Dyson Sphere.

Unless of course, gravity manipulation is part of having sufficiently advanced technology.

If you have such godlike technology that you can convert matter into energy, then you already have an endless supply of energy.

It's not completely endless. The stars are still converting large amounts of matter into energy, and you will eventually run out of matter to convert.

If you can disassemble whole planets, and can control matter with the ease necessary to fabricate your hypothetical (and impossibly dense) Dyson Sphere & Ringworld building material, then why would you waste it building anything that's tethered to the gravity well of a star?

Because you can?
