It's not competition in the CL that the twelve clubs wanted to stop. It's competition for the CL and the value of their teams that they wanted a closed shop. It's simple: look at American franchises. Some of the most terribly run teams in their sports are far more valuable than football clubs:

But that's what a closed shop does for you. A franchise system with no promotion/relegation, salary caps/luxury tax, and controlled purely by billionaire owners. You take away all downside risk. You can even get taxpayer-funded stadiums or threaten to move (local funding for stadiums happen in Europe too but it's in that club's city, not a move away).
A more closed Super League does two things:
-Guarantees a massive chunk of revenue from TV deals (guaranteed entry into the Super League every year)
-A group of owners decide on spending caps (no more UEFA losing to Man City in court)
These things would make a club like Liverpool far more valuable than it is today. It would also prevent teams like Real and Barcelona getting into further debt trying to compete with Abu Dhabi, Qatar, and soon to be Saudi Arabia. Set the rules of a closed shop.
The owners aren't worried about Atalanta or Leipzig in the Champions League. I doubt Florentino Perez's concern is that Real Madrid don't win the CL enough.
They care about how to make their clubs more valuable and to rein in the likes of Man City and PSG while they're at it. Some of the most valuable teams in American sports never win anything, but it doesn't stop them from being valuable. The twelve clubs that pushed the ESL would still win of course, but Spurs value would've gone through the roof in the ESL even if they never win it.
The one equation these owners ignored: the supporters. Oops.
Sound plan otherwise though. Certainly looks great on a spreadsheet or a future Forbes magazine article.
