This is what I'm thinking too. By default, you'll always want to store more copies of the file since you can't trust the uptime of the nodes in the same way you can trust the uptime of an EC2 instance or node backing S3. I think SLAs on trust of an individual node in the network are needed for storage to work. Compute, on the other hand, seems to have a really bright future with web3 as long as the workload/task is parallelizable (for instance transcoding a video which has been broken up into many HLS segments). This is at least based on how I work it out in my head, but I'd love to have someone school me who might know more!
