Internet is computers and communication protocols. Those exist. Bitcoin is not "used" given it doesn't exist. Numbers are attached to address by Satoshi's system. Attaching numbers is a proof that numbers are attached. Attaching letters is proof that letters are attached. Attaching a picture to a email message is proof that a picture is attached. No bitcoins magically emerge by attaching one thing to another. You believe in some sort of alchemy. Try to use your brains for a second instead of repeating the same nonsense over and over again.
Your level of your ignorance is astounding.
The Internet exists. Okay, I agree. But does the DNS protocol exist? It is also just a collection of numbers attached to addresses by your definition. Denying the use of Bitcoin is the same as denying the use of DNS. Could you please show me the DNS? No? You can't see it, hear it, or touch it, yet it exists and billions of people use it every day.
I think he will never admit that he is wrong about the fact that Bitcoin does not exist. He says that Internet is computers and communication protocols. OK, you can see and touch computers. But can you see and touch a communication protocol (like DNS in this example)? If you can't touch it, I guess it doesn't exist so I don't really know how does my computer know what web site to display when I enter bitcointalk.org into the address bar.
It can even go further than proving the existence of DNS. How about proving that "numbers" are being added up inside a computer. Can you touch a number that is running around inside a computer? Since numbers aren't "real", and they are just an idea ... what then is happening inside of a computer's processor. It really is just low voltages being compared from one transistor to another, a 0 volt here, a 3 volt there. Those voltages aren't "numbers". This then suggests that nothing is happening inside of any computer, and therefore nothing with a computer is possible, let alone communication via an internet.
Delusional minds derive delusional thoughts.
Here a quote from Bill Murray seems appropriate:
It's hard to win an argument with a smart person, but it's damn near impossible to win an argument with a stupid person.
