Actually the moon does rotate once a month roughly, but we know what he meant.

I contemplated spinning the Moon by using photovoltaic launching of mined metals into orbit for construction of the 100km space ship.

The Moon would accelerate in the opposite direction, but it would take petatons of launched material to get a slow rotation. It's easier to just haul the construction material up.

But it would be fun to build a "particle" accelerator around the Moon's equator, going faster and faster until at orbital speed, the load would be in orbit. During the last circling, the load could be held down until the desired orbital speed is reached, then release it and it would go up to the desired orbit.

Maybe the accelerator could get enough speed in just a few hundred kilometres. Or maybe even just a kilometre or so. The final kick to get the right orbital altitude could be from a compressed spring so that by conservation of momentum, the launching carrier would come to a stop = no energy waste.

With an orbital speed of only 1700 metres per second and launch speed of about 2200 metres per second, or maybe even up to almost escape velocity of 2400 metres per second an accelerator of 100 km length might be enough for hefty loads of maybe a ton. Perhaps 10kg loads would be better. Or various launchers for various sized loads. 7,000 km per hour is doable easily = 2 km per second.
