That's the point, even though bitconi when first created is not for an option of investment but people doing it on their own will anyway. Maybe it will looks doesn't make sense seeing bitcoin's price as a whole but bitcoin have the decimals amount and can be divided into pieces. Therefore it's still worth as a currency and investment.
You just don't need to be surprised seeing the high price, it can even go higher, just compare how much the total supply of bitcoin and the amount of "always growing" bitcoin adopters.
