I think it's weird to advocate skipping shots (not explicitly, but implied) because "everyone's already been infected several times". Best to just get them even if you've been infected and then you don't have to care if they help or not. As opposed to not having gotten them if it comes out that they do help in any way.
Also that was the only time I've ever gotten sick from covid. I guess that according to you, I must've been asymptomatic several more times.
