Arguments against bundlers always sound to me like a person who lives next door to their job saying "I don't get why so many people commute by car, walking works just fine".

That is - some projects don't need a bundler, and for those projects, sure, do whatever. I don't think webpack is in any danger of becoming the new jQuery, where devs add it to every project because they don't know how to work without it. People using bundlers are usually doing stuff that can't be done without them, which obviates the whole argument.
