Have you looked at the size of Youtube and Netflix videos?

According to this study [1], 70% of web traffic is video streaming. Only 8% are web browsing (which might include images, because they are not mentioned anywhere else - didn't find any info on that).

This is not going to make any difference.

Just because the vast majority of roads are for cars doesn't mean we should therefore not try to optimize the bike and pedestrian lanes.

Sure, a lot of the traffic is streamed data rather than HTML, but 30% of close to a zetabyte of data in a single day (for the internet as a whole) is still hundreds of petabytes that can be made drastically smaller. When the numbers are that large, even optimizing for something as "insignificant" as 0.01% of the traffic means 10s or even 100s of terabytes not pumped through the network every day.

You sound like you want to act for the good of the whole human beings but we have priorities over shaving the last bytes off our pages.

You would have a better day to let webmasters know to use gzip if they aren't.

As always: optimizations are not a matter a of "one or the other" they're about "do all of them". Make the build tool apply all optimizations and minifications, and make the client-server connection negotiate as much compression as possible. Don't stop at just gzip when further improvements are trivial (like this one).
