As someone posted that we don’t know what we are talking about, maybe you need to reconsider your travel strategy and protect the laptop a little better. Use a bigger bag, use a padded section or generally be more careful.
You're basically suggesting that I keep my Macbook on its own, absolutely away from everything else. Or just get a bigger bag to leave more room for stuffs.
That's doable as well. But that means I'm adding at least 1-2lbs to my travel gears. I did try that, too. That's how I know exactly how much weight is added. And any bumps will still cause the screen to hit the keyboard by the way. It's inevitable.
For me, I prefer not to do that when a super thin screen protector solves the issue and allows me to get away with having less weight overall.
It may be a unique issue but again... try traveling with 10lbs of other stuff (specifically: camera gears, clothes, essentials) in the same backpack as the Macbook on a regular basis and the issue will show up after a mere 2 weeks. You can wipe it all off the first 5-6 times you see the marks. After that? Micro scratches will show up on the screen (just use your phone or a flash light to shine the screen), and then eventually, the marks will indent on the glass (specifically, not the glass but the anti-glare layer) and then they will stick there. Forever.
Yes, I have been through this many times for years even up until now on the M2 15" Macbook Air.
Maybe people don't care enough. Some micro scratches shouldn't bother anyone. But I just prefer not to have to worry about it at all. I don't want to have to "baby" my Macbook. It's not a special piece of gear that requires special handling.
