I will illustrate my central point using the SEPA system you mentioned and forgetting the USA prehistoric finance platforms.
SEPA was introduced in iterations in 2008, 2009, 2014, etc. The EU has the resource means to achieve this in a way that other countries (e.g. development or underdevelopment ones) couldn't do.
Argentina, a super corrupt, infinite loop bureaucracy , and relatively weak country has implemented direct bank to bank transfer without fees (only taxes!) in 2001. This shows my point clearly. This was implemented in less than two years. Indeed around 1 year because they took one to work in the law.
Comparing Argentina to the EU (in political terms) is, in general, completely unfair. I don't know you but I would be concerned as a taxpayer if I were living in the EU zone.
