Well said. I'm also a little older and think exactly along those lines.
A mistake in building a feature is not the end of the world. If you don't manage to convince 90% of people at your company, then they will do it, with or without you.
And in fact, you should also consider that despite your absolute certainty that this is a bad idea, you also could be wrong. Maybe your product doesn't need coins at all, but funding wise it may be smart to ride the hype, just to get cash. It's not very classy, but business is not very classy in general.
