But 3 months later they come in to complain about the fact they've lost the equivalent of $100.000 they had in their exchange "wallet" due to a hack or phishing or an exit scam.
I understand what you are saying and I agree. I am just saying how it is. People start thinking about their security only after they were the victims of a hack/scam. We start to think and cheat like that from early age. I am not going to do my homework because there are 30 other pupils in my class. What are the chances the teacher will check if I did mine? And if you get a bad grade, you are angry at yourself for spending 30 minutes and doing the homework in the first place. You can apply the same excuses to matters of health, your own safety, etc.

Fair points, but if you don't know how a WIFI card looks like, Google it or watch a YouTube video of how to disconnect it. You can find YouTube videos on how to dismantle almost any model of popular laptops, clean them, and put them back together.
Working with Linux is a different kind of problem. That's not something a quick guide can teach you. But if you absolutely don't want to do that, you can stick with Windows because your system will be offline anyways. Linux is recommended, but it's not a must.
