In my opinion, the purpose of investing is not to create capital. The purpose of investing is to preserve existing capital. It is good for an investor if his investments allow him to preserve his savings from inflation.
yes that is true but we can also reinvest the money we gained from another investment and keep the money growing
i do not think there is just one right definition of investing neither there is just one way of investing because it really depends on the investor and what his capabilities are and what his goals are entering an investment
some may just want to keep their money safe from inflation, some may be planning to use the profit made for buying something huge, some may want to keep it growing and etc
