with all due respect. We have greater goals than another orbital outpost.
We currently develop a lunar base

"Calling the effort a "comeback to the moon," European space planners envision a series of human missions to the lunar vicinity starting in the early 2020s. Those missions, according to the plan, will include coordination between astronauts and robotic systems on the lunar surface. Robots would land first, paving the way for human explorers to set foot on the moon later. "
The ISS paved the way to this goal. There is no need to waste new money on a duplicate of it.
A space station makes sense for china, because it follows our steps. But it doesnt make sense for italy or ay other european nation.
We currently develop lunar 3D printing.
