The British Government had DMs, that's what they sold trying to keep their currency at fixed rate. You say they should have kept Deutschmarks to sell them later for what? For depreciated sterling pounds? It doesn't make sense, the only thing that a government has plenty of is its own currency. Governments are "rich" in their own printed stamps, the challenge is to keep those stamps valuable. That's what the British Government was trying to do.
