Nobody would ask for your ID, when you are purchasing ordinary goods and services(excluding weapons or alcohol). It doesn't matter if you are purchasing them online or offline. IDs are required in the financial sector and the gambling industry. Those industries are heavily regulated, because of the risk of money laundering and tax evasion. If you value your privacy that much, just don't open a bank account and never use an online casino. 
There's no way around those KYC rules and regulations. It's really difficult to stay unbanked in the modern day world.
There's no way around those KYC rules and regulations. It's really difficult to stay unbanked in the modern day world.The story of KYC began in the 1970s when banks (BSA) created it to detect and report suspicious activity. Its purpose was (and supposedly still is) to combat financial crime and money laundering. So, even if you buy general goods, cars, paintings, etc., ordinary things or services, KYC is already in you. You are marked from the start, whether you like it or not. The thing is that every time you will pass it again and again and again in order to "cross-check" you.
We all know though, that this didn't stop black money from moving around, bypassing the system. From 1970 until now, 54 years (soon 55) money laundry still exists and their numbers are bigger every year. Something is not working as they say it will...
