blockchain wallet app is not true bitcoin. its a service that uses bitcoins network
EG looking at a webpage is not the true internet. its just a page that uses the internet
saying using blockchains wallet app is easy.
is like saying looking at a webpage in1994 is easy.
but understanding the intricate details of how the internet actually works (DNS, ISP, IP, HTTP, FTP, SMTP) is the difference
people dont just want a flashy webpage that asks for credit cards. they actually want to know that its safe to shop online in the 1990's. they are worried about putting their funds/personal information out there onto the internet so they want to know about what http is as oppose to https and what makes https so much better.
same with bitcoin using a service is easy, but knowing if its secure.. they will want to know a little more then just the basics
But you don't need to know about Internet protocols to use the Internet. Realistically, most people don't need to know more than how to use a browser, Google, and their favourite websites. I doubt most people will download and install bitcoin core so they can use bitcoin. Most of my friends didn't even notice when sites went from HTTP to HTTPS, I've revealed to at least 10 people in the last few months that there's a difference between HTTP and HTTPS.
