I think the point is that it's not really a currency if nobody can print a menu with it as the denomination that is valid for even a month. MSFT or AAPL isn't a currency either. Sure, you can use it to buy money, but there's a reason no one even tries to accept it for a pizza.
To be a currency, I do believe you should be able to print it on price tags that change no more often than weekly!
In our community, "bad idea, well executed" is also a maybe - not a "fail" - on succeeding - as by definition if you're executing well you know when to pivot and aren't afraid to do so, or you are simply succeeding despite a bad idea[1], or are doing what it takes to push it through.
Also I'd like to point out that the definition of executing well is almost begging the question. To answer the question "Was it well-executed?", we apply the heuristic "Did they succeed? get numbers up? generate sales, investment, etc..". Then we are only 'testing' our own definition and every successful company will be "well-executed" and vice versa.
I'm not sure how to improve these definitions, but it's important to realize that asking how well a team is executing is problematic.
You would need a definition of "execution" that lets you point out teams that are executing well and failing, before you had a concept of 'executing well' that is useful and not just a proxy for 'succeeding.'
[1] Plenty of big, multibillion dollar product categories (McDonald's for one, two year mobile phone contracts for another), are a really bad idea. If either category didn't exist, I doubt an investor would think you could convince people to like it, on a national scale.
