Bitcoin gives freedom and privacy to it's holders that is why they're at liberty to either spend it as a decentralized digital currency or they can hodl it as an investment asset. Bitcoin is a new innovation in the financial system and it's not even two decades old, so you can't expect it's usage as a currency to be compared with fiat just yet, you have to give it time. I believe that in the near future the naretive about Bitcoin by those that are still skeptical about it will change, it's already happening, the adoption is increasing geometrically. Some businesses have started to accept Bitcoin, gradually more will join as the awareness and adoption continues to increase. Remember that great things starts from small beginnings and it's sad that Rome, wasn't built in a day, so it's not too late for you to hop on the train.
i appreciate your detailed comment, i agree with you on most things, but one thing is still a problem - the usage. The normal, everyday user doesn't know (and doesn't want to deal with) securing their coins in cold wallets. Once a mistake is done, the money is gone and no one can revert it. And it doesn't seem like the bitcoin community even cares about this problem. Decentralization solves some problems, but creates other problems.
Modern banks were created as people realized they were unable to secure their gold and silver coins properly, so they allowed a third party to store them and protect them, the issue is that this allowed those third parties to abuse their power and play with your money as they wanted, so we are forced to choose, do we want for that abuse to continue or do we take back our wealth and store it ourselves with the risk this entails? So it is not that the community does not care, it is just there is no good solution for it, you either pick one option or the other, but you cannot get the advantages of both by picking a single option.
