You've described how BTC can scale as a currency, but haven't addressed ardit33's first point, which is that not many people seem to want to use it as a currency in the first place.
I speculate that at first people want to use it as a store of value, but after a critical amount of holders, and having a lighting network, users and merchants could also adopt it as a currency.
A conservative scenario is that cryptocurrencies will not really become adopted other than store of value: I think even in this case BTC value can go up tremendously. It has benefits over gold: like easy and fast transport accross countries.

Why would they? Why should I buy things with BTC instead of USD? The fact that I've yet to hear a convincing answer to this most fundamental question is the strongest indicator that BTC is a bubble.
