If you only buy from Trad Catholics, you will starve and be homeless, naked, with no material goods or tools.
If you only read books from Trad Catholics, you will have no books.
If you only watch videos/movies from Trad Catholics, you will watch no videos.
If you insist on Trad Catholic professors, you will attend no classes.
See the pattern?
Trads are a thin sliver of the population, and most of them are wage-slaving away for "the man", NOT producing any content or goods to sell personally. Nor are they in prominent jobs like Professor or run prominent Youtube channels teaching this or that. Most Trads are lacking in such worldly ambition.
There just aren't enough Trads, and most of them aren't entrepreneurs, authors, or producers of content. There are probably only a few dozen such Trads worldwide. CathInfo has had 6,908 members past and present, and how many have written a book? Just Sean Johnson, that I know of. Are there ANY prominent Youtube channels on any topic at all, run by Trad Catholics? How many businesses are run by Trads? Now divide that into the number of small businesses in the United States: 30.2 million.
