Is this 「より」used to make a comparison in this sentence


I have been trying to work on my Japanese particles for the past few days. I’m
using a workbook titled “Japanese particle workbook” and I’m on it’s second
usage of より where it says it’s the “indication of a comparison”,however; one
of the sentences used as example doesn’t seem like an comparison much at all,
and I’m having trouble with the way the book is labeling and translating it.
Here’s the sentence with the translation: **新しい車を買うより仕方がありません。 There’s no
other way than to buy a new car.** To me it just seems that they took the
dictionary definition of より “than” and just used that for their translation.
Is this a nuanced sort of comparison that I’m not understanding that goes
beyond the English translation? I’m having trouble wrapping my head around how
this sentences より is used for comparison. Also I would like to note that that
the テレビを見るより... example using “Rather” in its translation may be throwing me
off a bit. [![enter image description
