For someone with money, "wealthy" is the obvious answer (and connotes various kinds of abundance).
For someone with social resources, "influential" or "well-connected." If you want to suggest that they don't often use these resources, but that people would do things for them if they asked, you might need a more specific term describing the nature of their standing, such as "respected," "popular," or "well-loved." If it's just because they're powerful, then maybe "powerful" or "important."
For someone with intellectual resources, a person who knows a lot of things might be "knowledgeable" or "widely-read," or they might be "a polymath," a "jack-of-all-trades," or a "renaissance man/woman." Or they could be "clever." "Clever" is sometimes used as a subtle insult (or as conspicuously faint praise) to refer to someone who has intelligence or problem-solving skills but uses them for trivial things.
In normal usage, I think the word is "traditionalist".
"Paleophile" would be a better word but I don't find it in any dictionary: it's not an accepted word.
- Very late addition and clarification *
If there is no well-known word that expresses an idea you want, you can, of course, always make up a word or use a word that somebody else made up and that only 10 people in the world know. But then you can't expect your readers to know what it means. You'd have to define it. Don't make up a word or use an obscure word with no explanation.
If you would only use this word once or twice, I'd say, in general, don't. Just use a phrase to explain what you mean. If you need to use the word many times so that using the same phrase over and over would be awkward, then sure, invent a new word, define it, and then use it.
Like, "These people are what I will call 'paleophiles', by which I mean, people who love old or ancient things. Paleophiles often ..." etc.
