I am from Nordic country. I did not use any cash, had no wallet for several years. It's not needed. After the US government acting like it does I mostly stopped using cards. Like with phone OSes a US-controlled duopoly.

Cash does not to need to be used anywere, but cards can be avoided for weeks until I need to use it again. Most can be handled by cash or bank transfer without problems.

For phones I have not any Google Android or iOS until a year ago. Nowdays I have a Google work phone, but it's always in flight mode except when a pay my lunch subsidized by employer. I type this comment on my Sailfish device and I use a degoogled Android. Can cause minor inconvenienance occasionally, but rarely enough to turn on my work phone.
