No one would waste time to watch the wNBA game. The wNBA is a good product for the level of athleticism present. People will pay to see the absolute best, not the best in the athletic class. College ball is popular because of sentimentality of the alumni and the families and traditions of the fans.
If college ball was presented as an elite league with no connection to alumni, they would fail also.
Prime example...the G-league.
You may be right but if it is a tie-in-sale so to speak and in order to watch an NBA game in person you must first watch a WNBA game, the WNBA will have a much bigger audience.
