I don't think you've seen enough photographers if you think what I'm doing is average. You're right that the barrier to entry is low, but so is the skill level of those just starting out. In my experience most don't have the drive to improve themselves much either. They just putter along, and their family and friends feel like they need to use them and that's enough gigs to suit them until they bore of it.
Make no mistake, if you gave my gear to someone that had little or no experience they wouldn't get the shots that I do. They would have no idea how to find good light, or in the absence of that use strobes or reflectors to create good light. Just posing people is a huge task. Some people are naturals, but most are far from it. Even if you know exactly how a person 'should' be posed, getting them to do it and be comfortable in front of the camera is tough.
After that is editing and retouching. Most low tier photographers throw on a preset and call it a day, and wouldn't have the first clue how to do anything in Photoshop.
I've had multiple couples that have done an engagement with me, and I later went to their house on their wedding day and they had several large prints up. Families have also ordered large prints of their shoots from me.
Most of my work isn't particularly unique, but I'm in a rural area where I don't have the amount of potential customers where unique work would sell. My strobe lighting is unique though - very few photographers use anything more than a speedlight. That lets me pull off shots that other photographers could never do. If you ever see a photographer claim to be a "natural light photographer" that means they have no idea how to use any artificial light at all. They're literally using ignorance as a selling point, and it's not uncommon.
One of the bad aspects of marketing in this job is that even bad photographers get lucky sometimes, which with enough shoots can equal an OK portfolio. There's also a disgusting trend of "workshops" where good photographers set up a shoot with lighting and paid models and photographers pay to take those photos for use in their portfolio. It's rare that I get asked to see a full wedding when someone is inquiring and it's by far the most important evidence of the skill of a wedding photographer.
I'd put up my senior photography against the best in my state, and I've been hired by companies like Hormel to do photography even though they have an in house team.
