From what I've read, it won't be as effective. Would you not be able to
get at least a season out of the mesh before it starts to tarnish? That
way, you need only clean it with regular tarnish removers every fall,
and reinstall in the Spring. Also, olive oil helps retard the tarnish,
so that would extend its life each season.

I've never used copper mesh myself. I've had great success with the
rough lumber and mulch. I'd be curious to hear of people's experiences
with copper.

I've read that you need at least a 3 in. wide strip (solid copper foil)
or the critters will cross it. Don't know about a 5 in. mesh, sounds
like it would work. I'm going to experiment with a 3-4 penny wide
barrier on a low-lying bowl of beer and see if the slugs will cross
that. Beer works great but the results are a bit gross and is more
effective at attracting slugs than snails (I've got both in abundance).
If pennies or copper mesh works I'd probably install it under a ledge
mounted on the edge of my raised beds which are made of 2" x 6" x 4ft
(or 8ft) redwood. I wasn't planning on removing any copper barrier I
install as I live in zone 9b and I plant winter crops. Slugs and snails
are year round around here. Pennies would certainly be cheaper than Cu
foil or mesh.
