Having just gone through the annual KYC checks required by my bank/s I don't think this opinion stands universally.
Can also confirm to open an account I need to provide a live selfie and verifiable government ID.
What is the "annual KYC check"? Your bank is afraid you became someone else during the year or what?
As always, the goal in convincing others is to take someone from their current understanding and bring them closer to yours. You can't get there if you don't start the topic at their current understanding of it.
This is a requirement for two different banks I have, very likely for the rest as well.
Doing the live selfie route I don't need to provide tons of other documents.
For banks without the live selfies I need police certified docs for ID and address.
And the big thing for KYC every year is proof of current residence.
