Bitcoin "is a fucking toy" when compared to VISA and yet in it's realm it has done quite well at being better than cash for many things. I know a guy who purchased land by taking it across international borders. I've used it multiple times for things VISA was not useful for.
By my measure bitcoin was a success and now it's outlived it's prime.
I view Monero and Ethereum in the same light. I'm sure you would have pointed out bitcoins flaws when it was $10 per coin and said "This will never work." out of some of the same principles you are using now.
You are one of those who peruse perfection and I wholeheartedly respect that.
But I'm not hearing any alternatives from you. And as you so graciously pointed out - I'm a n00b. I can't fix all the problems you point out. So my two choices are opt out of the market. Or pick the least bad losers. When I perceive them to no longer be the least bad - I will move on to whatever else is the least bad. I know it's not your strategy - but it's mine.
By your standards bitcoin was fundamentally broken years ago. But it paid off for those who picked "the least bad option."
BTW I wasn't the one who posted your stuff on the reddit ethereum forum.
