Do you think every good product idea needs to become a business?

Something I've been thinking about lately is how many genuinely useful ideas never get built.

Not necessarily because they're difficult to build, but because they don't make much sense as businesses.

An idea might solve a very specific problem for a handful of people. It might save someone a few hours every week, make an annoying task easier, or solve something that doesn't affect enough people to justify a commercial product.

But does that make the idea any less valuable?

I've noticed that we often evaluate product ideas through the lens of market size, scalability, monetization, and revenue. Understandably so, especially when building a startup.

But I wonder if that mindset also means we're overlooking a lot of potentially useful products.

I'm curious how other Makers think about this:

Do you think there's room for products that are genuinely useful but never intended to become businesses?

And if you've ever abandoned an idea because it wasn't commercially viable, do you think you'd approach it differently today?

Would love to hear different perspectives, especially from people who've built products or explored ideas that never made it to market.
