Yes, there are middlemen in Bitcoin, but there are also ways around them, unlike in banking.
And yes, I definitely trust million of men who are constantly checking each other, rather than 10 bankers who found out that sticking together makes them more money.
That fraud argument is a double edged sword because I might be on the receiving side and falsely accused of fraud as any small business hit with chargebacks would confirm. When it's sent, it's sent, that's how it should be, no backsies. In the CC world you never know. Plus there are also escrows if you really need them, except unlike in banking world, Bitcoin escrow won't force you to eat a 30% haircut on your savings account when the bankers fuck up the whole economy while paying themselves big bonuses.
Bitcoin is actually more expensive than SEPA transfers or girocard payments, and slower to resolve (and just as impossible to reverse as SEPA transfers).
Which bank is this? Since 2014, SEPA-ICT has been introduced, and since this year, every bank should support it.
Normal SEPA transfers are mandated to be free and < 24 hours, and SEPA-ICT transfers are mandated to be < 1.5€ and < 15 seconds, but most banks implement those for free.
As you can freely choose any bank in the EU, you might want to consider German Commerzbank, which implements free < 15 seconds transfers to any other SEPA bank (except for student accounts, those have to pay 1.50€ for those transactions).
Anyways, it's about how much money you're willing to spend for trust/safety/risk-mitigation/speed.
Cost of item - $100
$100.05 - pay via Bitcoin. In case of fraud, suck it up.
$102 - pay via Bank. In case of fraud, complain to bank, who are slow to resolve it.
$105 - pay via CC, (and pay them via Bank). In case of fraud, complain to CC company, who are faster in resolving it.
Both Bank and CC are basically an escrow service. One provides a bit more security than other, and correspondingly charges more for it.
If you're OK with not needing that security, cut out the middle men.
Going along your analogy lines, cut out even the Bitcoin middle man, or any kind of currency, and directly barter/trade goods.
