In general I agree, but it really depends on the idea, product, branding etc.
Movie ideas can be sold for 6-7 figures.
So why wouldn't something more developed than just an idea also be valuable to someone, ie a good fleshed-out business/product idea and some development, trademark etc, but not yet online/no paying customers, etc.
Because the world is full of ideas. 99% of them are bad and worth no money. The way you prove it is, is to go implement it and see what happens.
Movie scripts are sold for 7 figures if you have written multiple 7-9 figure movies. Which again, is proof by doing that it is good. If you or me spends 6 months and write a banger movie script, I doubt we can sell it for $250.
Not necessarily, 'off the street' movie ideas do indeed sell.
And good ideas really are not worthless, though I agree 99% are just not good ideas. This industry would have you believe that ideas are nothing, because their business is funding idea development.
And the assumption is a web product. Of course it's difficult to gauge if a web product is going to work, and you should just try it because it's relatively easy. For real products, this doesn't apply so directly. In some ways it's easier to see if an idea is worth trying out or not, and since it's harder to actually test a real product idea, the idea better be good.
And I'm specifically talking about more than just an idea, particularly some product development and branding.
