Nah, that's nonsense derailment about government.
The idea that some malevolent government could simply change words and control the people is fiction.
What Orwell was warning against is
complicity with societal dysfunction stemming from corrupt government.
That is, when
we change the meaning of words to countermand their correct and/or mislead, then we're in trouble.
No, there isn't a word for everything -- but there are
idioms (which may be a single word and not necessarily a group of words [a
phrase]) which we can use.
And there need not be a word for everything. We get along just fine without one. Making up words doesn't tend to help either. Why make up a word (like
capraphobe), which would serve mainly to confuse people (because they would have to stop and try to figure out what you are saying) instead of just saying "fear of goats". Same number of syllables, same meaning, less confusing.
You would think, given sites like these:
http://www.goat-trauma.org/ that there would be a useful made-up word. Somehow, it escapes them to have one. Why? Because it doesn't matter enough to make up a new word for it.
Clarity of expression is more important than having a new word for it.
A
spoonerism is so called because it is named after a well-known university man who did it all the time.

The way new words come about is by resonance with some subcultural cohort -- it is instantly understood, makes sense, has the right feeling, twist, or humor, etc.
Or if you are someone like Noah Webster.
