I don't login from new computers often, I have my personal machine and mobile phone. It's great to be able to login from a phone without needing a password manager or manually typing a 50 character randomly generated password where I need to be sitting in front of my main computer to even login. If you really have that many computers you'd still need to sync a password manager between all of them to login with a password.

I also don't browse with incognito mode on sites where I'm expected to be logged in unless I have multiple accounts that I want to have logged in simultaneously.

I also don't routinely switch browsers and if I do I only have to login once per browser and I'm done for a year or however long the site saves it for.

That doesn't sound like insanity to me? I didn't even think about them while writing my original reply because they are such outlier events.
