I don't disagree with you, renting is certainly easier and more lucrative. But another counterpoint to consider is that you're getting another person invested into the SPL ecosystem. This is another happy DAU who is glad to make their earnings as though they were playing Axie. Granted Axie payouts are better, but the more invested people you add to the ecosystem, the greater the chance there is to thrive.

Notice how Axie really took off once they went to Ronin and were able to do scholarships, it's gone to the moon since then. AXS was under $1 last year and is about $110 now. Small steps help us see the same sort of success in SPL one player at a time.
