Oh yes, but there is plenty we can do about it, pal. We can choose to run software like Knots that allows us node runners (who set the rules everyone has to follow whether they like it or not), to kick out all of your garbage, non-monetary spam.

And the awesome part is the game theory will make it so that less and less people over time will run bogus nodes that have op_return bloat, and instead will opt out towards Knots instead.

Folks like you will simply fade into irrelevance as Bitcoin only becomes more efficient as a monetary technology.
