Well, for an anecdote, the process of renting an apartment was considerably easier in UK when it came time to send in payments.
In London, once I'd signed a lease, the rental agency simply gave me account numbers for the deposit and other fees. I sent the payments to UK from my Finnish bank account at no extra cost (bank transfers within the EU/UK payment area are free).
In New York, once I'd signed a lease, the rental agency told me I need to bring them seven cashier's checks by Monday for the deposit and various fees going to different destinations (condo management corporation, etc.) At this time I was in London, so shuffling physical pieces of paper from a bank into an office in NYC wasn't going to happen! Kindly the agency agreed to allow me to wire them the total sum, and they would "cut" the checks for a mere $15 / check. For seven checks, that was an extra $105 fee — for nothing really except to work around a system still built on 19th century assumptions of money. (I also had to pay fees to send the wire transfer, because Americans somehow believe that bank transfers cost tens of dollars to process.)
Additional patchwork layers like Venmo don't solve these issues. Sending thousands of dollars to a landlord or management corporation isn't the same as sending $50 to a friend for dinner.
