This was followed by a nice discussion of how to use swarm agents to generate an island of your own to solve the problem of real estate taxes that I had left hanging to some degree.
I can think of a couple of problems:
(a) You need the "rights" to the land you are going to develop
otherwise you may need a large collection of designs for nanodefenses. I'm not sure how the UN handles "claiming" new volcanoes at this time (or whether it has ever come up.) (b) Unless you allow the large scale construction of the island to take a very long time, you are going to have to exceed the 10 kg nanobot operating limit. Now the oceans have a huge ability to serve as a sink for this, but warm them up too much and I think you destabilize the methane hydrates causing a rapid release that causes a huge increase in the greenhouse effect. Scientists believe this may be the explanation behind some of the previously unexplained warm periods.
Which points out a general rule that I think needs to be invoked when we consider what to do with nanotech -- we must "play nicely", this could also be called: "don't piss in the sandbox if you want to play in it tomorrow".

If you are going to play with Mars, it makes more sense to dismantle either Mercury or the asteroids first, turn them all into solar collectors and use most of the solar output to completely dismantle the planet. Time for Mars disassembly: 12 hours. Then turn the material into O'Neill colonies and give one to everybody.

I think it would be nicer to live on some nice, moderately small vista close to your friends, while supervising the assembly of nanotech reefs that could serve a shelters for small fish to promote the repopulation of the oceans?
