The usual reason given is that they get sun damaged.

Its basically true, they wont last as long left outside all the time.

I've plenty of experience of old brittle plastic pegs. A lot of
plastics and UV don't mix

But the OP mentioned a peg bag. The bag should be UV-opaque for that
reason, and can be left hanging on the line or post.

Yeah, but then you have to put them in nd take them out of the bag,
quicker to just leave them on the line.

Slower.. you have to wipe the line to remove the dirt before you put the
clean washing on.

Why would leaving the pegs on the line have anything to do with wiping the
line?

Because you have to take them off the line to wipe it.

Can't say I notice any great problem with the line being dirty though.

Obviously depends on how grimy the area its used in is.

And how well it weathers too.

Occasionally I give it a quick wipe if it's not been used for sometime (at
least weeks, which doesn't often happen with 2 adults and 2 children)

If you don't the wife will notice when she irons and finds dirty marks
where the pegs were.

1. I deal with all the laundry

2. We have better things to do than bother with ironing

Yeah, me too. Havent ironed in something like 55 years or more.

(or be bothered about the odd dirty peg mark on the odd item of washing)

Its not so much the peg mark as the full line you can get
with stuff that's hung over the line before pegging it with
stuff like T shirts with a line that's got a deteriorating surface.

Corse the line is so cheap it makes sense to just replace it
when that starts to happen, particularly when in my case the
line is between ring rawlbolts in the block wall of the house
and ring bolts in the metal fence on the other side of the yard.
