The vast majority of transactions are from people buying and selling crypto, not for real world cases, just trying to make a profit in fiat.
We've had 15 years now, and we can still ignore crypto. Most people do. I chose not to, in case it made me rich, and it seems to be working ok towards that goal.
I don't see what you mean by "giving up", because that is still presupposing that there is a real problem that the technology is solving, that people are ignoring out of laziness or spite or something.
