>Indeed. An actual free-trade agreement would be really simple to implement. Just stop intervening in trade in any way, and you'll have Free Trade.

Is free trade even a good idea?

Suppose industry in your country has higher costs, because people care about say, waterways, and thus there has to be filtering and proper waste disposal.

If you allow free trade from a country where they simply dump waste everywhere, you are punishing industry for doing the right thing, and rewarding polluters.
