Ideas are worthless.
The phrase "IDEA has no value" has lost much of its context and is ambiguous. Examples of context-supplemented
Ideas without execution are economically worthless, so it is difficult to sell the idea by itself at a high price.
Ideas that are not registered as patents are worthless as property rights, so you can't charge them with theft.
An idea that the person thinks is a good idea, but in reality has not developed at all, has little chance of developing even if it is kept in the chest and believed to be a good idea, so it is better to talk about it with others and use it as material for generating new ideas.
This isn't "worthless", it's "low value".
Ideas that are merely untested hypotheses that "might solve the problem this way" are less valuable than solutions that have been verified to solve the problem
relevance
The story says that people who generate only a few ideas estimate the value of their ideas too high.
