I work in multiple OS and physically multiple countries, frankly you will not gain access to these networks without a level of AV/MD
That's an absurd argument and you know it. Clearly if someone says, "you need X to enter my property", you need X, but not because X is actually necessery on its own (which is what the OP is asking about), but because someone has just written it down as a requirement.
again you are assuming my usage meets yours, it doesn't nor does many others.
You really need to quit saying this. I've already stated,
now for the third time that this is correct.
I've assumed not a single thing about
your usage. I've only stated, (again, repeatedly) that anti-virus is by no means whatsoever a necessity for Mac users simply due to someone using a Mac to make money, which was your original claim, and is exactly what I quoted in your original comment.
Protecting your data and livelihood makes sense
And wasting your time and energy on something that isn't a problem makes zero sense.
if you as an individual do not have need of third part security solutions, so be it, equally others do and some need advice to do the same, data and or time loss is an issue for many.
WOW! As I said, you keep going on about not assuming things about others, then repeatedly fail to heed your own advice.
I make a living on my Mac as well. Never had a virus, and have not needed anti-virus software. And I find your insinution that, just becuase of your false assumption that I'm not professional, that data loss isn't an issue for me to be extremely offensive. I have decades of irreplaceable photos and videos, and thousands of dollars of media that I would be devestated to lose.
A/V software isn't about data loss or time loss. That's what backups are for, and I'm well covered on that front. I could be hit by ransomeware, and be quite fine. There would be time loss of less than one day, and no work loss as I'd pick up on another device until the restore is complete.
You really should quit assuming everyone's case is like yours.
