Just talking about bitcoin, and not about this specific situation or their adoption: Bitcoin has some minor advantages in technology because the financial industry is slow, but that's not the major reason to adopt. The major reason is trust.
Historically, it's difficult to trust many organizations. The US federal reserve and the US dollar have the best record/reputation in modern history. Top competitors have taken devaluations in WWII and even recently (British pound in 1992, Russian ruble in 1998). That's part of why many people use the dollar. Even now, after 2008, when everyone thought the currency was screwed because money was being printed fast, we didn't see inflation. But the dollar isn't perfect. As recently as the 1970s and 1980s the US dollar experienced double digit inflation.
Bitcoin is an alternative currency with less trust in a central authority. It's got a bunch of other features like you've both been talking about but it's real value add is the lack of central authority (both in terms of volume of currency issued and in terms of your ability to hold your own currency without a 3rd party).
Now, maybe you don't want to use Bitcoin now because you believe a problem with the US dollar or any other local currency is a 'low probability event'. That's totally reasonable. But it's also worth remembering that humans are known to be bad at estimating risk/reward from low probability events. Historically speaking, there will be a currency crisis in the next 50 years. I can't think of any fiat currency has ever gone 50 years without some sort of currency crisis (at least of the ones we have a good historical record of). Bitcoin aims to be the first one to do that. We'll see if it ever does.
