I'm struggling to understand the compatibility of the MimbleWimble backbone + unlimited supply:

For a potential "everyday use" cryptocurrency that dominates the global economy, I think some rate of inflation/emission is 100% necessary.

But I don't think Grin is trying to be that with the way everything else is situated. The elimination of denominations and addresses makes this currency fundamentally difficult to interact with. I also think an inherently private coin would be incompatible with the role of worldwide day-to-day use.

I don't see any other situation for Grin or any crypto where unlimited supply is a good thing to have. What's the justification?
