Which term describes anything reasonably regarded as economic gain or advantage?

The term that best describes anything reasonably regarded as economic gain or advantage is "Benefit." This is a broader term that encompasses various forms of advantages, including financial, social, or practical gains. Benefits can result from a wide range of activities or investments and can present themselves in multiple forms, such as improved quality of life, enhanced productivity, or increased income.

In contrast, "Profit" specifically refers to the financial gain after all expenses have been deducted from revenue, and is a narrower financial concept. "Asset" describes resources owned by an entity that have economic value, providing future benefits, but it does not directly imply a gain or advantage in the economic context. "Revenue" refers to the total income generated from business activities before expenses are subtracted, which again does not necessarily reflect a net gain or economic advantage. Therefore, "Benefit" captures the essence of economic advantage more comprehensively.
