Because it reinforces the fact that access to bitcoin generally requires a bank account. Everyone knows it is possible to transfer bitcoin over the internet, the key part is that nobody will do that for free, so an exchange must be facilitated and facilitation of exchange over the internet nearly always requires a bank account.
> you could do a remote job and be paid in bitcoin if you really wanted
A luxury available only to tiny fraction of the population, and even then, it's difficult to find substantial work where one is paid in bitcoins without a lot of searching (all the cryptocurrency focused job boards are ghost-towns full of trash and scams)
> Or sell goods/services via Open Bazaar [1] and receive bitcoin
Totally impractical - Open Bazaar is a ghost-town and there are no marketplaces with more activity besides darknet markets (and I've actually tried to sell stuff on OB and seen this first-hand). Also 2-3 multisig is not a solution to the problem of fraud which has an excellent risk/reward ratio for scammers on markets like Open Bazaar.
Sorry, I don't follow then. You asked how you get it without a bank account and I believe I answered that. Why does it matter if I have happened to purchase my coins via an exchange using Euros? Why would you think we would have to meet up personally?
As for your other comments, well I was not suggesting that Bitcoin, or crypto, is ready for this right now. The original point I was replying to was that there is no use for it at all when I think (it was an opinion) - that there is potential in the technology. I am imagining the "if", in the spirit of the original comment, not the current reality.
No bank account needed is true in reality - you could do a remote job and be paid in bitcoin if you really wanted. Or sell goods/services via Open Bazaar [1] and receive bitcoin. None of this might be "good enough" for you but it does exist. We are also far, far on the left of the adoption curve, so yes, I agree there's a ton of stuff to make it more practical than it is.
