this is a kinda strange example, since the discovery tends to be government funded research, and the safety shown by private money
the USSR went to space without those protections. its not like property protections are the only thing that has driven invention.
MIT licenses are also pretty popular as are creative commons licenses.
people also do things that don't make a lot of money, like teaching elementary school. it costs a ton of money to make and run all those schools, but without any intellectual property being created that can be sold or rented out.
i dont believe that nobody would want to build much of the things we have now, if there wasnt IP around them. Making and inventing things is fun
