Australia for example can purchase via CoinBase BUT they can't sell it. There's a fair-few countries that are also limited to purchasing only.

(not sure what they mean by "convert"... maybe that means swap between coins)
Yep, I was right:

An AU player (for example) would need to acquire another crypto-wallet. Hence, I don't think coinbase is a good option for AU players. I use CoinJar (there are others), and this allows me to sell and either send to my bank, or transfer to an ATM card (up to $999 per 24 hours). Or I can buy other crypto coins. CoinJar now have PayID (OSKO - instant bank transfers).
The idea of putting together videos, and help pages to assist players who are not crypto savvy is great. Maybe a little more research on which crypto-wallets are best suited to specific countries, will help boost signups and retention, even more
