The fact that Chrome automatically disables extensions that don't exist in the web store, in the name of security, is probably not a good sign. If it is for security, then advanced users should've been given a way to bypass this restriction, but it doesn't exist. If the adblockers get removed from the store, there would be no easy way to use them without abandoning Chrome.

- You switch to another browser that allows ad blockers or has a good one built-in.

Ah, but not when all the (Google-powered) apps and services you use only work on Google's browser.
