Because Google doesn't want you to do that.[1]
Use Firefox. The Web works just fine with all Google tracking blocked.

(Of course Google could do the other thing and say "ok since you clear all cookies, we log you out of Chrome, so you lose sync etc." but it's probably _not_ what most people want, nor what Google wants).
Oh well. At least it makes it dead-simple for the advertising company to track your complete browsing history.
PS: Install cookie autodelete, install uBlock origin, disable chrome login/sync entirely, and disable "enhanced" safe browsing. Block the google domains from loading globally on sites in uBlock. Also, and I cannot stress this enough: stop using gmail. It subjects not only yourself to total ad surveillance, but every single person you correspond with.
not sure if this argument is valid here because that third party cookies issue still happens in incognito mode where I'm not logged in to my Google account.
I like Firefox but didn't find this feature.
