It isn't out of line to suggest it, sure.
You literally just said:-
The suggestion of "retiring" the advice is out of line on that basis.??
As for retirement of a meme, I'm not really expecting the community to retire anything or a meme to die. Truth be told, this was a bit of advice specifically intended for an individual in anticipation of a situation.
And in regards to strategy.... everything is strategy. No matter whether your skin is financial, personal or political.
I'm only aware of one clear instance where the advice became a meme (on twitter recently) and I took it as being quite amusing. To view that as a problem shows lack of appreciation for humor IMO.
I seriously doubt that fluffypony is going to answer any differently when people ask him in interviews, etc. whether Monero is a good investment or whether people should buy it, but who knows I could be surprised. I won't be recommending it to grandma any time soon either (unlike, say, Evan who apparently recruited most of his family to 'invest' in Dash, and that has indeed worked out for them, so far).
In that case I'm out.
