A transaction like this is just a glimpse of what the potential is for BTC and crypto. For it to 100% succeed and become fully adopted we need for it to be convenient to use for the several small transactions people will be making day in day out (like buying their morning coffee for example). We need it to get to a stage where it can withstand millions of people making these transactions day in day out seamlessly and cheap.
bitcoin is not designed to be used for people to buy day to day coffee so unlike what you think, it doesn't really need to have that capability "to succeed". bitcoin is aiming at being a decentralized, censorship resistance and boarderless payment system and is succeeding at that. and this is why it has a lot of potential and the current price drops don't matter at all.
with that said, bitcoin is now have that capability to be used for day to day "micro" transactions by millions of people through the second layer solution called Lightning Network. and already some merchants have integrated it in their system and have been accepting payments for months.
