Way too many people still don't understand that this is an essential part of the security equation. Many sites execute 10+ scripts, many of which are doing who the fuck knows what, and said sites typically only need like 1 to 3ish allowed to function.
Sure it's inconvenient compared to not doing anything, but it's mostly front loaded inconvenience. Once you get things dialed in for frequently used sites, and learn to tell at a glance what needs to be allowed, its really not much hassle at all tbh.
