I've never spoken for my personal opinions towards Bitcoin in this thread. Actually, I challenge you to quote me wherever (you think) I did. Those things I've told you are facts.

Money is debt. You measure this debt in money. Fiat currencies are money, because they're considered by people as currencies. Two individuals could setup their own ledger which would contain their own transactions, in simple “numbers” as you say.

For instance, me and DooMAD. We could create a ledger that starts with 10,000 monetary units and deal by using this as a medium of exchange. Say DooMAD gave me a bar of chocolate, I signed in the ledger that I now own 10 less and he owns 10 more. If more people liked this ledger, it could be considered money. Yes, they're just numbers, but it's a lot easier to transfer the equivalent of ten Teslas by writing down some additional lines, than by transporting the actual vehicles. Therefore, it satisfies for this purpose.

But, that's what I'm telling him for the past page. The problem is that he can't understand that it's a wrong conclusion to consider something meaningless just because it's a number in some database... It satisfies one job. Therefore it has at least one purpose of existence.
