Thing is while yes teams can anti-strat there is actually 2 problems i can see with it.
1- Experience against it. Look at teams that struggled against PRX and teams that can shut them down, the teams that can are very used to the aggressive style as they literally are scrim partners, while NA and EU can def have good plans on paper, thats the thing, on PAPER. Any team can anti strat an aggressive, thing is if they barely have any experience fighting one they would falter really quickly which brings me to my 2nd problem
2- Aim. PRX have undoubtly some of the best aimers in the world, maybe not THE best but some of the greatest. To beat them you would have to either outaim them, or completely change up your playstyle and i mean it, look at how DRX and ZETA played against PRX, both had to basically 5 man flank or 5 man guard site to absolutely counter PRX, and i would say in the west barely any teams can do that successfully, as again they do not have any experience against it, with maybe the exception of Faze but their style of aggression is different from PRX.
