So I think some people like to get verified.
What about it? Is this a justification for doing something so stupid? You can manipulate people to undertake just about any decision and they will fight you to the death with the claim that they have made that decision on their own. Some people also like to do heroin, but hey that is randomly different and we can't use it as a justification for doing heroin?

Its not that people like to be verified, its that they don't think about what are the drawbacks and the dangers of doing that. At least not until they get screwed (and even then many don't learn their lesson.
You are assuming two things. Firstly that people have any knowledge at all about these matters. Secondly that they have a capacity to think about the consequences of complicated systems and scenarios. Neither is true. A person who understands these topics could never answer with a "I don't care" type of answer. This indicates that they don't understand the subject matter at hand. Now if you eliminate those that don't know anything about this, those that believe that they do with their coping answers of not caring and those that are unable to think deeply enough to deal with a matter like this you are left with what? 10% of the population? 5%? 1%? The situation of the modern society is much worse than pretty much anyone is willing to admit.
Am I comfortable with sharing KYC data with casinos? Absolutely. I mean, it's not like I would be comfortable with that if only online casinos were asking for my data, but living in a world where everyone, small shops, medical centres, post offices etc are selling my data to whoever they want, in that world, yeah, I'm comfortable with sharing KYC data with casinos. I even think it's a bit safer to share my data with them than with some organizations I'm sharing my data anyway.
Nothing can force you to provide your data to any of those. The only things where you must provide data are essential services. For everything else it is only your stupidity that leads to the sharing of your data, nothing else.
¯\_(ツ)_/¯
