Bitcoin's use will never be for that. The current system used for day to day shopping works perfectly. The banks and the payment processors that are established are all giving efficiency and convenience to their users so Bitcoin has no place in it. Where Bitcoin thrives and will thrive more is in the black market and online dark markets simply because the banks do not serve that space.
So basically you think that bitcoin is only good if you are a gambler, tax evader or black market user?
I do not consider it only good. It is a really excellent tool for doing illegal stuff online. Have you seen the interest from ransomware using hackers? It is increasing. I will not be astonished if we find out that different terrorist groups are using Bitcoin as a tool for value transfer.
And if you actually want to do something constructive and increase utility value for customers you shouldn't support it?
You know that this version of protocol is not the final version and in the future we can have huge changes to how bitcoin network will work, right?
That is not what I said. As a fellow Bitcoiner of course I want it to be used by the mainstream. But the question is, is there a need for it when the current system that was put in place by the banks and the government is already efficient and very convenient for everyone in society. Meaning if the banks serve a market space, there will be little to no need for Bitcoin. So what space does the banks refuse to serve? Those are the gaps Bitcoin will fill.
