In my opinion this is a pretty stupid "mindset". Bitcoin was created by Satoshi to be used as a CURRENCY. Sure people stack currencies in order to appreciate/stack wealth, but people also use currency as a means of payment. In my personal opinion it is important to use bitcoin as a currency to help it's adoption in to mainstream, world wide success. Anywho..I don't know about you, but for me, life isn't free and bills have to be paid..so selling some at times isn't that big of a deal.
Wrong.
Have you read the original whitepaper? No where in the document, Satoshi says that Bitcoin should be exclusively used as a currency or as a mode of payment. Satoshi designed Bitcoin to fight the current economic system, which is dominated by the central banks. If you want to change the system, then you need to consider all the sectors. Focusing only on the payment method is not going to resolve the issue. I could understand your concern, if the usage of Bitcoin for payments is getting affected. But that is not the case and therefore I don't think that there is any significance in what you have said.
