You are not really saying anything different from me, yefi, yet can't we concede that there has been a whole hell-of-a lot of development, adoption, and even public consciousness in bitcoin between 2013 and today, yet perhaps bitcoin grew from .05% to .75% of world adoption. Great progress, but holy shit far from being able to serve anything like a currency - even while liquidity is way better, so for example, from almost anywhere in the world, if you can get an internet connection, you can transfer various amounts of money for almost free an no one can stop you.
Of course, some places it is going to be difficult to figure out how to cash out your bitcoin, so there may be some fees involved, but bitcoin definitely gives options to people - and peeps are going to come to this better mouse trap, even though it could take 50 years for people to figure out - including getting distracted by the multitude of shit coin imitators who are building and selling fake mousetraps.
Technically we can't concede, because we've never resisted or denied those things

. Bitcoin growth and development has been amazing. I could not have wished for more when I joined this forum five years ago.
You are right also, we appear to both be paraphrasing a point that the currency function will emerge naturally as a result of Bitcoin's continued growth. The lack of that function at present is no reason to dismiss Bitcoin.
