In fairness, step (2) isn't essential. What they're hoping for is that bitcoin gets increasingly adopted. Part of the value of a currency is that a portion of the currency is 'dead'. If we're using bitcoin, we'll all have a bitcoin wallet. Oh, at any given time, we're going to spend any specific bitcoin. But at any given point in time, there's a certain amount that's not being used. Not because it's being hoarded (as it is now), but because it's just not being used 'yet'. Think of it like the float in a savings account. Any specific person might not have much float. But the total float is pretty large.
A lot of bitcoin's current value is in place because it's being hoarded. And people are buying it merely hoping that it will rise in value (rather than having utility in its own way). Current hoarders are just speculators. They're happy to sell to a 'greater fool', but the chain of the greater fools is hoping that bitcoin will be adopted. Individual buyers are only buying 'hoping' that it will go up, and only think it might go up because it's gone up before.
Now, bitcoin might become like gold. People have psychological feelings about its fundamental value. At that point, it becomes a store of value. Everyone just hoards it, but only because everyone else is hoarding it. And, like gold, we waste vast resources just hoarding it.
Bitcoin has real value. It's just not an investment, because buying bitcoin doesn't create any value. In finance, one of the greatest swindles was tricking people into conflating 'investment' with 'savings'. Bitcoin is absolutely a type of savings vehicle.
