Glekichi, looking where you want to plant it may well work for carrier arrivals - I dunno because the closest I ever came to a carrier landing was watching 'Top Gun'.
But it definitely works a treat on rough, unmarked, irregular, one way bush strips and those with obstacles all around which can create illusions if you look anywhere other than where you want to go. Some PNG strips slope up so steeply that if you looked at the far end, chances are you would be flaring at 100 feet.
As for whether those of us who did our early few thousand hours on tailwheel Cessnas and DC3s and the like are "all hopeless in a crosswind" - we would not still be here if that were the case.
The Jacobsen Flare has its place, and we were taught more or less this technique (long before Jacobsen published it) for night landings on a flare path with no glideslope information at night.
But how about we accept that other techniques work better for some of us?
