Look up the definition of “eradicate”, and also note that you’re talking about a parasite. The best (read: cheapest) hope for “vector controlling” mosquitos until the malaria parasite was extinct globally was probably DDT, until it was banned.
Just because we didn't eradicate human feeding mosquitoes doesn't mean it wasn't hugely worthwhile to play the game of controlling them.
Coronaviruses are definitely not in that category.
If/when we have another, more damaging pandemic, I expect the lesson about how powerful a tool social distancing is to sink in more widely (we are somewhat accidentally having a mild flu season so far; just changing attitudes about what is appropriate when symptomatic would be a benefit, you don't need to do big lockdowns to benefit).
