I did read the article. They can't succeed with thirty players.
Based on my quick google search, G League players make up to $35k a year
OK, didn't seem like it from your post. The authority has spoken. Nothing to see here.
That is in the process of being changed.

"California high school star Jalen Green, the No. 1 prospect in the 2020 ESPN 100, is making the leap to a reshaped NBA professional pathway program -- a G League initiative that sources say will pay elite prospects $500,000-plus and provide a one-year development program outside of the minor league's traditional team structure."
They are planning to expand the number of players getting big salaries in the G-League.
Anytime.
The question becomes if the G-League gets most of the Top 20 players, who will be left for Overtime?
The article speaks about a "rotating roster" of players instead of teams. That could make the teams more like pickup teams. Your team mate today is your opponent tomorrow. IMHO, that would hurt development of team focus in the players and make it more about the "me."
Will the kids be willing and able to learn to play team defense if their team mates change frequently? Games could look like high school all-star games.
