Its cargo probably is worth a lot more, though ($130 million divided by 20,000 containers is $6,500 per container)
Egypt first would need a court to judge that its claim is valid, and then probably would sell it.
And if that doesn’t bring in the necessary amount, Egypt still would have a claim, and likely would seize any other ship from the same order that passes through the canal (possibly even ships that aren’t in Egypt)
1) It was towed up the canal a short way to a "lake" area for inspection. It was leaking immediately after the grounding, and probably does have minor hull issues, but no update since it was freed.
(Steel ships rely on the forces of floating - having water push up and inward to maintain the hull shape. They're not designed to be grounded or to be allowed to sag in the middle.)
2) It was never out of Egypt's custody.
