Much of the damage apparently has come from tape used to put up signs and placards at the Capitol

So, the Marble was damaged by "Tape"? Where did the Capitol buy their Marble from, Walmart? Harbor Freight?

How can Tape damage Marble? Unless it's taken off with a hammer and chisel....

Have you ever tried putting tape on genuine marble and putting it out in the elements to get damp and exposed to sunlight?

If you go to the cemetery and look, you will see that those headstones made of marble tend not to last long. It is used because it is a beautiful stone, not because it lasts as long as, say granite. And yes, do not use marble in your kitchen unless you have lots of money or eat out a lot.
