To be clear, that doesn't mean that a simple solution will never be created. Obviously we think it will, but that doesn't mean we're right.
But to address a slightly different part of your framing, our situation actually got more complicated when attempting to go the legal route. We suddenly had additional lawyer, collections, and time costs associated with the process...and we still never managed to collect. That's certainly an area where the current legal system fails (for a lot of people!).
Cryptocurrencies might not be the perfect alternative, but they are an alternative that, in our opinion, is exciting to explore.
