You use eID when explicitly interacting with a govt entity or bank or otherwise similar institution because you have to and want to prove who you are. Yes, I do want to prove who I am when I file taxes, vote or want to start a business...

You don't use it when just browsing randomly on the internet. You don't use it to buy games on steam. Your computer isn't forced to store it because a law arbitrarily says so.

I usually buy games on steam using a process that does involve my bank, do they actually take bitcoin or cash posted in an envelope?
