Yes, I'm sorry.

I think the collectors will be lighter than our spacevessel the Asimov so
their final velocity will be bigger than that of the Asimov. Adding some
weight may help, but the total collecor should become at least 100 times
heavier than the Asimov which is not very practical. Recycling to Mercury
may not be so nice, the shear forces may rip the 10 km array apart. (I'm not
sure how close you want to get)

While building Rome, people had direct profit, namely a save place to live.
Building a "big rocket" may only give them a job, but who's going to pay them.

Don't thank me, it my job :)
