Now I've shown no long-term movement with 2 masses, you can expand the calculation for 20 masses. But why 20? Why not 10? 100? 2?

nope , you didnt show anything except that you have a clear understanding in how to sudgest something will not work using incorrect assumptions.

we are using 20 masses because that is what we started with.

20 masses being accelerated will push the pipe with a greater force than 1 mass being accelerated.

besides I didnt want you two guys to get a even start so
I used 20 to start with.

we could use just 1 mass to prove it will work, and you know it.
