This is the point of the post, to the average bitcoiner, it is just investment and profits and never on the utility and how bitcoin is making our daily lives easier just like every other technological innovation.
I can't blame anyone for seeing it as an investment. Also, I personally can't see how Bitcoin is capable of assisting us in our daily lives. Certainly, holding Bitcoin has been a huge plus for me, as I'm capable of having money in my wallet without involving banks or any financial institution, while allowing me to accept payments from signature campaigns etc.
I have always been advocating against holding Bitcoin because if all we do is buy and hold Bitcoins, then how will Bitcoin grow? I believe that money has to be in circulation in order to develop the economy. If we regularly use Bitcoin for payments, then more and more stores and companies will accept Bitcoin payments, the more we see Bitcoin Accepted and this will help Bitcoin to grow but recently things have changed and I've changed my habits, now I promote Bitcoin holding because if you see, governments are starting to keep their reserves in Bitcoins, more and more companies follow MicroStrategy's plan. We shouldn't give our Bitcoins to governments and big corporations, we should hold them tight.
Although I'm seeing your point of view, it's not that easy to expect stores and the general public to accept Bitcoin. Yes, its initial purpose was to be used as a currency, but whether we like it or not, it's rather inconvenient. See El Salvador's experiment, only a tiny percentage of their population is using it.
