Users could just move to another platform without artificial scarcity and... stay there, because there is no scarcity.
I'm not sure that coercing people to settle is positive behavior, but regardless, enforcing artificial scarcity isn't a feasible strategy for a dating app.
You’re equating more choices with better outcomes. I argue that isn’t the case. Unless we’re going to feed every data point we can into a ML black box, and out will come your arranged ideal partnership (there’s even a black mirror episode about this).
Getting to know people sounds more fun, but I’m old shrug
To be fair though, if people could be convinced to buy into the platform with its restrictions, it could make for an interesting experience.
While Tinder profiles are built for speed, with only a few pictures and blurbs, profiles on your platform could have much more detailed biographies, videos, etc...
It would be a more immersive experience.
If done right I think your idea does have potential.
