Basalt remesh is available for sale.
Made from stone fibers, it's immune to rust.
It's not cheap,yet.
But it isn't outrageous.
Could it be a great substitute for steel or plastic mesh fencing?

I looked at your link.
I think the products from that company are related only to the concreting business.
In areas where the soil is acidic or you have marine [ salty ] environments precautions need to be taken to
prevent corrosion [ rusting ] of the reinforcement, since the reinforcement is an integral part of the strength of concrete.
The bags of fibre mesh are mixed into the sloppy mix and replace the need for steel mesh, its my guess at this stage the actual mesh shown is for situations where fibre mesh is not strong enough.
IE dome structures
From their information

The construction industry is becoming aware of the existence of reinforcing bars made from fiber-reinforced plastic.
Fiberglass rebar has been on the market for some time, making inroads where steel rebar doesn’t work well.
The first common applications have been used in corrosive environments and places where the induced fields resulting from steel reinforced concrete structures exposed to high levels of radio frequency radiations are a problem.
There is now a new entry into this field, rebar made from basalt continuous filaments.

Basalt is a common volcanic rock, found throughout the world where volcanoes have erupted and sent lava to the surface. It is actually present everywhere at a depth below the surface

The actual mesh you spoke of appears to be steel mesh, with a resin coating and I believe for the application it is being used in, ferrocement domes, its perfect, but I think for fencing good quality galvanised mesh would be better.

The mesh is indeed created for the concrete business.
But it's made only of basalt.
Here is another example of the same product from another company:

The corrosion resistance is what is attractive for our purposes.
A nonplastic mesh barrier that will not rust, made from nothing more than rock, could last for centuries yet eventually return to the earth.
It comes in coated or uncoated

Well, I have to say I am amazed at this product.
As the link says "Our basalt mesh combines a best-in-class tensile strength and natural resistance to deterioration from alkali,
and weather extremes. Comprised of single-ingredient basalt-rock melt,
this basalt scrim is significantly stronger than fiberglass and steel wire mesh."
