Creating an open market for compute, labor and goods that would compete with AWS, Amazon and the gig economy would be a good place to start. These groups skim a large portion of companies/individual's profit.

Yeah the difficulty isn't even thinking of a good idea, it's reconstructing the enormous legal barriers, government contracts, and relationships with private capital that the existing tech companies have cemented over decades.

The larger barrier will be coming up with products that people are willing to pay for.

Thats one way to market yourself, but not the only way. For example, consultancies don't come up with products people are willing to pay for. They are hired as a service to do work on a project, but they aren't selling things off the shelf. A software "consultancy" could operate in a similar way, where customers say "we need engineering labor to achieve our goals" and this agency comes in with the labor that develops the product to meet the companies needs.

My org is starting with B2B SaaS products. If you can move these into a cooperatively managed framework you drive long term value while also building networks with successful businesses. It's a major opportunity because so many B2B SaaS platforms are super overpriced. The client companies are basically overpaying in order to pay back the VC investors. If you start out without any of that overhead you can offer a completely different funding model.
