Well, every journey has to start somewhere. Wireless charging as of today may not be perfect or for everyone, but if you want to get there some time in the future, you need to start gathering real-live experience. People and markets need to be given time to adopt to something new - cultural changes often need to be slow in order to be successful in the long run.
This is about far more than about saving a few seconds from not having to plug in a device for charging. Think of the possible ubiquity of charging options without the hassle of carrying a cable with you. Not shattering your phone coz the cat tripped over that cable again.
And - I do admit - the sheer convenience is indeed just great (even a few seconds can make a difference, when accumulating day-in, day-out). And for many, no matter if old, dizzy, tired or in low-lighting conditions, wireless charging can provide a real advantage indeed.
As for environment: By your argumentation, Battery-Electric vehicles should not be purchased and driven yet, as they‘re far from being the perfect be-all, end-all solution. But you have to start somewhere.
Besides: Apple is said to be working towards a device with as little moving parts and ports as possible. Wireless charging is mandatory for this scenario.
