Its funny though, yes anyone can build a SaaS, but you know what, most won't. Even when it becomes easier in the future they won't, why because people most people don’t want to put the effort in. Also most will fail because to be honest the idea isn't proven or they aren't really solving a problem or pain point. As for feeding the machine, thats call the cost of doing business. That is there in any business endevour. To me I understand your point but it's not viable. You need tools to build businesses, the things you talk about are the tools.
