Not true. Limestone suitable for mining is a limited resource. That's why cement companies like Lafarge pay millions for mining rights in South East Asia. They clear out entire mountain ranges to turn into cement.
They will mine wherever they can make the greatest profit.
That doesn't mean we will ever run out, or even ever run out of good-quality limestone. It just means that for a variety of reasons (mostly lax taxation laws and a population in poverty that will work for terrible wages) Vietnam is a hotspot for mining in SE Asia, but its total production is a rounding error compared to what is produced in China alone.
There is a lot to be discussed about exploiting poorer areas for resource extraction. It's a subject that goes beyond any one particular resource. But (in the case of lime) it also does not imply scarcity. Keep in mind that lime can be regenerated- the lime cycle is an endless loop.
