Yes. Going even further, how much does the average user of cash understand about where that piece of paper came from, and what it really represents, what it really means. They don't and they don't need to. The central banks and governments have over centuries created a wonderful abstraction over all of that complexity, and reduced cash to a completely usable and comprehensible token of value, which literally everyone can use without a moment's thought. A lot of bitcoin's complexity is rather thinly veiled by the current generation of clients and platforms, but it's basically just a question of time (maybe a lot of time), learnings and improvements until this gets better. Whether bitcoin will survive this period of time is a separate question, but that the complexity can be successfully abstracted away from eventually is inevitable. It's testament to the quality of the abstractions that cash and credit cards provide that we do trust them and use them without thinking, and wonder how we could ever switch to an alternative system that doesn't offer the same. But there's nothing intrinsically less complex about them, and there's no reason why bitcoin can't get to that point too. Always keep in mind, bitcoin's only been going for a few years - it's an incredibly young technology and ecosystem!
