Because this is a fixed Norwegian pattern for setting up a contrast between two considerations. It works much like on the one hand ... on the other hand in English.
So the sentence is not just listing two random nouns. It is framing them as two competing factors.
Here, ene means one in the sense of the one ... the other ....
So:
- den ene = the one
- den andre = the other
It does not mean the only in this sentence.
This is a very common Norwegian pattern often called double definiteness.
When you have:
- a definite determiner like den
- plus an adjective like ene or andre
- plus a noun
the noun usually also appears in the definite form.
So:
- den ene siden
- den andre siden
Compare:
- den røde bilen = the red car
- det store huset = the big house
So den ene siden is the normal structure.
