These are not startup ideas, but activities that people do. A startup-idea might be to find a way to make these activities easier.

To make this list more useful, there should be two additional datapoints: 1. How many people does the activity impact 2. How much does the activity impact each person. The product of these would be the total impact. Sorting by the amount of impact would give the most valuable areas for innovation, and there should already be a plenty of businesses focused on these activities.

What's missing is a resource that would let you understand each activity, it's tools, processes, problems, etc.

Actually, if you Google them, you'll find the ONET page for the job descriptions that includes the activity and has more information about the task, e.g. https://www.onetonline.org/link/summary/51-8011.00 (tasks are the 'startup ideas')
