I love how you compare Bitcoin to SMS.
I could send an SMS to a number, and anyone could be reading it, and I could even have no control over whether or not the message is seen by others, or even delivered.
When you send Bitcoin to someone, you actually sign over ownership of that data. I send you 1 BTC I actually authorise to transfer ownership of that 1 BTC from me to you. And I know only you get it, only you can access it (unless you shared your access or you use someone else's access).
Yeah, and you are still talking about numbers. There are no ownership rights on numbers. When you calculate 1+1 you're using numbers and you are not required to pay something to someone. Nobody owns numbers. Nor you need someone to secure them given you can create them in an instant when you need them. You people are spending money on something that you literally can create in whatever amount whenever you want. But hey, it's a free world. You can do with your money whatever you want. If you want to purchase numbers, go for it.
