As you got to experience, smart phones aren't mainly phones, they're mobile computers with a phone app. They have Bluetooth that let's them connect to bikes close by, biometrics that let's them be used for relatively secure payment, modems that allows them to communicate with servers, GPS that makes it easy to see that you're not riding or parking the bike where you're not allowed, etc. If one person was able to unlock multiple bikes who is responsible for how the bike is used? A while back someone on a rented scooter hit an elderly man and then left the scene. He was found and convicted, because the scooter was personally rented by him. Don't expect to be able to use modern services if you don't want to meet the providers where they operate. It's like refusing to use a card and demanding everyone to use cash, you're going to limit yourself and it's your choice if you think it's worth it. I think limiting your goods and services to people with devices that have been available for more than two decades and are basically ubiquitous is a reasonable thing to do, considering the benefits that comes with it. Personally i very rarely talk on the phone, that's never been why I've used mobile phones. I listen to music and use offline maps with GPS far more, but I also use it for payment, camera, text messages, etc.
