You can do that, yes, but if you are going to need too many profiles (Over 10, I would say), your best option is to use an anti-detect browser or something like Camoufox. If it's under 10, the application has proxy support. But outside that, there a many use cases. I use it to privately browse the web, separate my personal and professional accounts, and manage links. If you have multiple accounts and you open a random link, you have an option to select where you want to open it.
