  1. We could create a partial Dyson without disassembling Earth. We could do a 1% Dyson using only the asteroid belt, leaving all of the planets intact. Or we could disassemble Mercury and create a larger partial Dyson. Just keep in mind that 1% of a Dyson sphere is generating more energy every minute than we do on Earth in a year. Also, Dyson shellworlds are science fiction. If we actually built a Dyson sphere, it would either be a swarm, or a belt of individual objects connected with flexible tethers. And yes, we could live around the sun in O'Neil cylinders, and when there is a billion times more living area in those than on Earth, a single acre plot of land on Earth will become the equivalent of expensive beachfront property. Once we have a portion of a Dyson sphere, we can start using 'starlifting' to draw materials off of the sun to assemble things without ripping planets apart. No, we aren't going to run out of sun. First of all, the Sun is very big. Second of all, by drawing heavy elements out of the star, we prolong it's life, actually increasing the time the sun has left to live. Once a civilization has a Dyson sphere, they can travel wherever they please. They can use giant death star lasers powered by the sun to push huge spaceships around at incredible speeds, and those ships can colonize other star systems and eventually build other Dyson Spheres. To give you an idea of the scale of a Dyson sphere, take the almost 8 billion people on Earth today. The Sun could support as many Earth's worth of people as there are people on Earth today, and every single one of them could live in luxury with their own 100 acre plot of land, while still having plenty of room left over for social services. With the amount of energy left over, you could support 99 more of that same civilization at the same time for billions of years, and have a generous amount of energy to spare. How much energy to spare? Enough to build an aircraft carrier sized spaceship every second, and power a giant laser beam that is to the death star what the death star is to a kid with a laser pointer.
