"Single dollars" is still a nosebleed-high fee for a simple electronic value transfer. Consider that pricing on something like an ach transfer is quoted in fractions of a percent (so like 75 cents for $100 USD sent - and caps out entirely at some low value like $5 per transaction regardless of the payment size.

International ACH transfer ? Any international Wire or remittance in general will cost you at least 25$.

And you have to get permission from a bank to perform the transaction.

There are cheaper forms of transfer, yes, but there are also much more expensive forms of transfer. A wire transfer will cost you $25 or more and yet there are still millions of them sent per day.
