A new entrant wouldn't necessarily need to compete worldwide; they could exclude any jurisdictions with regulatory or payment integration challenges.

The easy path to PCI compliance would be to use something like the Stripe iOS SDK and never see any payment card data. Agreed there are still some risks with card processing, but it's nothing unusual, millions of businesses deal with card processing.

Overall I agree it's not easy, but the challenges seem like normal ones that many startups deal with, mostly in smaller and/or more competitive markets which could never dream of the revenues or profit margins that would be possible here.

We could also look to the PC market to see that quite a few businesses do find it worthwhile to avoid the 30% charged by some stores. E.g. Epic Store undercuts it with 12% fees (7% if using UE), and larger companies tend to sell to consumers without using third-party stores, like EA, Blizzard, Adobe, etc.
