Modders who do want to get paid eventually become developers. And the best part is; some continue to mod for free even after they become developers. Who wants to charge for mods; it stops many people from experiencing their skill, who don't have the money to. Those free mod authors who do have a donation pool may have them filled. They may not have them filled. In the end it depends on the charity of people. And faith. Lots of it. I support a pay wall, but I'm not blind to its glaring problems. One is I would not be able to afford a single mod. At least not now. Besides, I'm a staunch believer that one does what they do not because they are getting paid for it, but because they'd rather do it for free than suffer doing it for all the money in the world.
