...nobody is using it in commerce...
There are many reasons why this has not happened on a larger scale yet, but just because there isn't a large STEEM/SBD economy right now isn't a reason to scrap the SBD token.
As I wrote in my post about this - we shouldn't be reactionary to short-term issues. We need to think long-term.
Also - there isn't much commerce...yet. I'll have an announcement this week that will hopefully start moving things in the right direction.
So how the long-term thinking is showing right now? I see only dreaming. There is no real vision, no actionable steps towards it.
Long-term thinking means that there is a clear goal and people are working to achieve it.
You're assuming that people are not working to achieve any commerce goals. I think that's the problem here.
I think everybody can see it pretty easily: so far basically nothing has been done.
