How much I pay for the DNS system isn't relevant to the discussion. Do you think it's free?
Let's get back on topic. Do you now deny the existence of Bitcoin or do you imply that it is too expensive?
I deny nothing. I am simply stating the fact that Bitcoin doesn't exist.
And I am saying that it is stupid to pay money just because a number will be attached to your name. Paying for communication via internet is reasonable. That's why we pay our internet providers. Paying for swapping numbers between addresses is not reasonable. So, it's pretty simple.
Yes, bitcoin is intangible. Everything is digital. What's your point?
Has anyone here ever claimed otherwise? But just because you can't touch it doesn't mean it doesn't exist.
Can you comprehend something so simple? 
My point is what I have wrote: if you say that 5 digital(intangible) books or movies exist, you are not supposed to show number "5". But books and movies.
In the same way, if you say that a specific number of digital (intangible) bitcois exists, you're not supposed to show number, but digital products. However, all you can show is a number. Essentially, you are proving that bitcoin doesn't exist.
