I understand from technical point of view, the transaction function is very important, but there are other aspects more important than transaction function. Anykind of alt-coin can provide transaction function, litecoin even designed to process the transaction faster than bitcoin. Crypto currency's value is not only decided by its transaction function
Gold is not good at providing fast and large transaction, but that doesn't stop it from being the monetary base of world's bank for centuries, because it has superior consistency and stability, no one on the planet can change the character of gold, no matter how big power they have
With Bitcoin there is no reason we can't have both fast and easy transactions and a store of value at the same time.
Maybe that is possible, but don't be too greedy and reqire too much at a time
Currently you can not reach that goal without a hard fork, and a hard fork as you have seen in recent event, is a very dangerous thing if not planned and handled very well
