I'll take some time to adapt to it, no doubt. But I don't see anything that could prevent people from getting used to it.

When it comes to wages: it's not that much of a change. Nowadays, people have to fight with teeth and claws to get pay raises or face poverty. In the deflationary utopia, people will have to fight with teeth and claws to not get pay reductions. It is exactly the same thing: protecting your purchasing power. The fact that the numbers are going up or down is pretty much irrelevant.

On the other hand, I'm pretty sure people will be very happy to see prices falling. Specially financially responsible people that save money.

Finally, it doesn't really matter that much if people are gonna swiftly adapt or struggle: they will have to. As Saifedean succinctly states: "History shows it is not​ possible to insulate yourself from the consequences of others holding money that is harder than yours."
