More than that, if they don't coincide with price S/R, they likely won't hold. i.e., they'll be irrelevant.

The fallacy of this statement lies in the presumption that S/R is something derived on its own. It is not.
S/R is determined by price reversal. When price pulls back from a rally into new territory, the new high is considered resistance. When price sells off and runs into the 200 sma, it's support. When the 62% FR is reached, there will be resistance.
S/R is dynamic, not static. Again, if price rallies to the 50 sma, and pulls back, R=50sma. If price then pulls back to the 20 sma and reverses, S=20sma. Now I ask you, did the 50 sma "coincide" with Resistance, or was it Resitance? Did the 20 sma "coincide" with Support, or was it Support? In both questions, the answer is the latter.
Sometimes an ma is S/R, sometimes a trendline, sometimes a previous extreme, sometimes the open or close, or a gap, and yes... amazing as it may seem... sometimes it is a fib retracement number, including 62%.
It is not a matter of which came first, the chicken or the egg?
