You're throwing the baby out with the bathwater, though. Waiting a week still prevents a decent amount of attacks. Not every attack can evade detection for two weeks. Even if it did, security scanning tools might still detect them.
Say hypothetically that 20% of attack slip through, which is still worrying, you can mitigate 80% of attacks by just waiting a week. It's a low risk, high reward strategy.
