The analysis seems to miss an important point about the difference of space- zero gravity. I am in the southwest and there are several solar installations in our area and the panels are mounted on some pretty elaborate framework. I wouldn't be surprised if the support structures rival the cost of the actual panels.

In space you could use extremely thin panels with little or no support.

There are already laws that handle this.
If one robot harms another robot the owner of the damaged robot will sue for damages. People will want to buy robots that aren't a liability so engineers will work safety features into the system. Insurers will not want to insure dangerous robot so robots with good safety records will cost less to insure.

Amazing how this stuff works!

I think the battery life is a deal breaker. Suppose you fall asleep with the watch on and forget to recharge it- you get on the subway the next morning and notice it is dead. Now what? It's kind of embarrassing to be walking around with a dead watch so you take it off and put it in your pocket and it falls out or you forget where it is or you sit on it and its bands are mashed up. After this happens a few times the watch will be sitting in your desk drawer.
