Joe, you are twisting the words of the Rambam. He says (Mishneh Torah, Talmud Torah, 3:10, and thanks to R’ Eliyahu Fink for the translation):
Anyone who comes to the conclusion that he should involve himself in Torah study without doing work and derive his livelihood from charity, desecrates name, dishonors the Torah, extinguishes the light of faith, brings evil upon himself, and forfeits the life of the world to come, for it is forbidden to derive benefit from the words of Torah in this world.
Yes, in Hilchos Shemitah v’Yovel he goes through the benefits that the Levi’im got, and says that anyone can get the same benefits if they want to dedicate themselves to serving Hashem. However, in his commentary on the Mishna (Avos, 4th perek) he lays out exactly what benefits those are. He also says that many people twist words to allow themselves to learn without working to earn a living at all, and that it is completely wrong. He maintains that even someone who is learning needs to have some kind of business/job in order to support himself and his family. He brings as proof the fact that the Tanaim and Amoraim all had businesses to support themselves.
Congrats, Joe. You are doing just as the Rambam said – twisting words to mean what you want them to mean.
