They aren't necessarily bringing payments or anything else like that. Just adding the ability to easily sign with your connected wallet. This brings lots of functionality. It could be used for logging in, community votes, encryption, admin key sharing (sharmir secrets), shared community wallets. Imagine you have joined a guild in a game that has a guild bank with a bunch of tokens and nfts of game items, these could also be managed in discord with voting and payment streaming done via chat, and when you rage quit the discord server your share of the bank accounts assets is transferred back to your individual wallet. You start a discord server and you have an instant co-op spun up with accounts, voting systems, and membership structure all in place. Thats attractive to gamers/activists/the local church group/political parties/etc. (and despite what the other commenter says, that sounds much more interesting and has more possibilities than worrying about paying for groceries)
