This is patently false. My bank, Fidelity, lets me send domestic wires (which are virtually instantaneous) for free. (Fedwires actually cost most customers virtually nothing.) International wires aren't that much more expensive, with the majority of the cost for small transactions being antifraud. In that respect, every cryptocurrency is orders of magnitude more expensive than the status quo.
Perhaps your bank is different, but googling "international wire cost" brings up links like these:

Just google it though. It's the most common way to send moderate sums of money in the world. And yes, pretty much any retail bank or credit union will offer wiring, probably for a fee.
