I feel like a lot of scientists have been saying this. Maybe not as explicitly, though, which can be part of the problem. Even Fauci keeps talking about how we didn't really lock down hard enough.

It makes sense. If individuals are supposed to quarantine for two weeks when they're exposed, then if everyone quarantined for the same two weeks, it would be gone.

Obviously you can't do a true, 100%, lockdown like that, but the logic is there: the harder the lockdown, the shorter it needs to be; the looser the lockdown, the longer it'll be before this thing gets better.
