We only need ordinary people like you and me to start using Bitcoin in any way each person would like.
People aren't really "using" bitcoin and probably never will. As a currency it sucks, but long-term holding as a store of value is where it excels. Everyone should be aiming to just hold a as much as they can afford for as long as possible.
For now, using it as payment method is not rampant so to speak because of considerations such as high tx fees, duration and convenience.Most are just holding it for the very reason of getting high profits.
I made a
topic one time as to the major reason why investors, firms, business owners and government are beginning to get involved into Bitcoin, which is valued on the profits to be made. Aside this profits, we won't have as much investors interested in Bitcoin because as you stated not an absolute idea for making payments on trades and services due to tx fees which isn't something stable, goes up and down to a point where the fee can sometimes be unbearable.
If it weren't legit, Bitcoin wouldn't have succeeded to where it is now despite the criticism from when and how it started, surprisingly Bitcoin has been a merit to anyone who has participated and likely has to put those negativity ablaze.
