Computers and cars are both solutions to problems, but the complexity of computers is yet to be routinely contained without targeted effort. This is especially true of the Web. Wordpress is the single most installed CMS (and kitchen sink, at this point), it's a massive attack target, and it's installed by people who don't really know what they're doing. Between being a kitchen sink (and having to deal with the internal/external API/architectural [compatibility] baggage that comes with any long-lived implementation) and having to be the CMS equivalent of Windows/macOS, it's a... difficult ask for a WP installation with (say) 30 poorly-constructed addons to to run smoothly. Possible, yes, absolutely, but it'll need tuning. Caching is simply the simplest bandaid that can be tacked on. If the caching is tuned properly, it'll fix everything else. Yes, this will mean the underlying configuration/state will be the digital equivalent of a giant wound you just want to clean out and fix up, but, err... it works. :/
