Actually, there might be a use for trapar... but only on a short-term basis. Use it as a cover over Valles Marineris and terraform the valley before terraforming the rest of the planet. That way, the Marineris opal miners can work in relative comfort until the valley is flooded - inside has Earth-normal atmosphere, outside has Mars-normal atmosphere. And if there are any problems with the terraforming process itself, they'll show up "in testing" when the valley is terraformed.
Heck, it might even pay for itself, depending on how much Martian opals sell for...

them. Adversaries remain citizens of the same state, common subjects of
the same sovereign, servants of the same law."
