> Patent == monopoly

For a very specific definition of monopoly (in particular, monopoly over use of a specific resource, not monopoly in the market sense).

In that same sense of the word "monopoly", private property == monopoly.

Can you sell your house 20 times while still living in it?

No,and you can't sell a patent 20 times and still own it.

You can rent your house out an AirBnB 20 times while still living in it, and you can non-exclusively license your patent 20 times.
