to be very honest, this experience isn't much different from early days of bitcoin. It's only recently that fees have gotten exorbitant and we've had to invent layers to fix that.
Bitcoin in 2008 was as good for remittances as it is today - it's just easier to acquire and costlier to move (lightning being the exception). However, it manages by ignoring all regulations (Indian examples: [0], [1]). Whether these laws are just or proportional in a world where information moves at the speed of light is a question for democratic processes, not multinational corporations to answer.
Payments via SWIFT are slow not because the bits transferring money over SWIFT are much slower, but because international remittance regulations are genuinely complicated.
