Erm, free movement of goods and services, labour, capital. Access to the world's largest single market with no restrictions which by itself allows more UK businesses to thrive. Huge benefit to being able to choose from numerous places to live and work. The UKs trade swagger is demonstrably worse without free access to the single market. Numerous academic studies have shown that long-term the UK will be worse off. Trade is the big one.
