Changing the names of those things isn't going to accomplish anything. You could always try traditionalist societies, though, if you really dislike manufacted foods. Become Amish or Mennonite or even fundamentalist Mormon and you won't bothered so much by these things.
Anyway, some words I think we actually could effectively get rid of, either because they have no empirical referent or because they are overly ambiguous, are:
Race, alien, ethnicity, religion, faith, love, history, etc.
One thing to mention, though, is that this isn't always the case. Some languages do primarily use more precise terms, like the many different brands of love in Greek that I believe better captures the intentions of the speaker than the single word used in English. One thing about English, though, is that it makes heavy use of modifying words. For instance, we'll speak of "brotherly love" or "fraternity" rather than "philos" and "romantic love," "erotic love," etc. rather than "eros." Fusional languages like this can be useful, especially literarily, in that they easily lend themselves to the use of metaphor and imagery - the devices can be far richer due to the double and triple entendres implicit in ambiguous root words without their usual modifiers. The problem we encounter in most of the English-speaking world is that metaphor can become confused with reality. Also, rather than appreciating the rich pregnancy of terms that can mean many things depending on context, people simplify down to a common definition for all possible senses of a given word, resulting in a good deal of misunderstanding, especially when engaged in "debate."
We could always switch to using Loglan, or even a natural language like Armenian or Cherokee that is far less ambiguous, but again, I think we would lose something literarily if we did so. English can be difficult to use to its full potential, but when it is, the results can be quite astonishing.
So I was wondering how European people related to the "Hedonians".
