I don’t use one myself for much the same reason as you. But I think a lot of people just need their phone and up to 3 cards (credit card, license/ID of some sort), so a wallet phone case isn’t that much bulkier than a simple phone case. Yeah there’s other things you’d put in a wallet, but they aren’t strictly everyday carry things, so you can put them in a separate wallet or purse/bag and only take that when you need it.
For my mom I think she just likes a case with a front cover, and it happens to have space for cards so she uses it. So the “bulk” of it is a direct result of what she’s after (the front cover), it doubling as a wallet is just a bonus.
