This is a misunderstanding of open source. Just because you share your research does not mean there is zero benefit to doing that research. There is significant benefit to getting the answers you need. There’s a lot of groups that would value getting their research done even if they have to share it, including universities and public healthcare research institutions outside of the US. Requiring that the information be open would not starve nasa of customers, it would simply attract different customers. Forcing the research to be public could have significant benefits to the world.
