First principle: It is not of you business how I use my money with other consenting parties.  You might not think it's useful. Good for you.   It's not your decision.

Second principle:  Smart contracting comes from BITCOIN. Those other systems are clones of Bitcoin, that chose to hype up some parts the copied or expanded on.  Their investors-- which may well include you-- routinely act to undermine Bitcoin.  Including perhaps, through subversive manipulation campaigns on social media to hobble bitcoin's functionality.

Third:  Those other systems are generally technically incompetent massively premined frauds.
