I use android so I'm already past that point sadly, but I'd be the first to dump my Google credentials as soon as that monopoly that's got a stranglehold on Android cracks
The block in degooglifying is usually region not lack of willingness. Some places are locked to Google by no fault of the consumer.
YMMV but I don't find having google wallet is that big of a deal nor a big enough conveniency to maintain a google account on my smartphone. A physical card is quite small.
