Going through mass bleaching events every 2-3 years is not the "whew, let's relax" event you seem to think it is when corals don't hit reproductive age for ~3-10 years, depending on species, with initial reproduction rates being slow and taking time to accelerate (the longest-lived animals on Earth are coral colonies, with certain individuals documented having lived for thousands of years; most live for decades, or in some species hundreds of years). Let alone the knock-on for all the species that depend on healthy coral for their their habitat, which lead to balance in the ecosystem, which is critical to e.g. preventing explosions of coral predators.
It's like taking an old growth forest in an ecosystem not adapted to regular fires, and burning it down every couple years. There will still be "something" living there, but it's just not going to be the same ecosystem it was.
