Actually. I think reading comprehension is the culprit here. I am not in agreement with you, and my post firmly states that. (Although I believe you were actually being cynical/mocking in your post out of spite or prejudice to an opposing voice to your opinion (Which is base and uneeded).)
To simplify, FFXIV exists on the premise of a theme park as Xatsh has so nicely noted YoshiP for in her/his above post: As with anything regarding business, marketing is a largely contributing factor. Advertising is a good example of what I am referencing in defence to your stance on game content. Advertising knows very well what it takes to sell someone something for X price and make them like it or believe they liked spending their money on it. An MMO is no different.
Now let's add those two analogies together, a theme park and marketing/advertising:
FFXIV serves main attractions/themes to its player base. Some players are not asking for those rides to be torn down, rather more interesting concession stands to be added alongside the main attractions. Concession stands with appetizing food, which will make them feel like they have spent their time/money in an appropriate way. Now let's broaden that concession stand into the form of what is being requested in this thread. Instead of merely a concession stand, some ppl want a restaurant, complete with more options and a nice theme which enhances the social aspect of dining. <--- Dining can be done solo, however, incorporating elements that allow strangers to socialize over a meal, is more appealing to some than others.
This is the premise of EXP Camps. Players want the freedom to use the landscape in an adventurous way instead of viewing it as some static landscape with inherited functional yet unused aspects. They want to feel "alive" due to braving "danger" when journeying from one point of interest to another. Such an element creates its own meta game if implemented correctly.
So I do NOT agree that social engagement is purely on the players. I am of the opinion that it is more so a combination of content with the correct advertisement/mechanics which allow/enforce social interactions. As in commercialism, it is by design. We humans are simple in some things, and our attraction to entertainment devices are one of those areas in which we are easily attracted to if the design is very well done/thought out.
