This is true. There can still be some funding for recreational aesthetic mathematics, like you can get some funding for various art projects or philisophy, literature, poetry, general humanities and community-building projects or sports funding or things like that. But currently many mathematicians are funded by the public purse with the understanding that this contributes to science and engineering and technological development at some point. I'm not saying that intellectual pursuits for the sake of human mental satisfaction is not worth funding in a society. The question is the amount of people needed. Tax payers pay for it. You have to tell them why, and why so many people need to be funded to do that. Many people have various hobbies they enjoy. But generally they don't get government money for doing it as the general rule. Maybe in a post-scarcity world.
