What you're saying is that your simple needs are filled by the worst photography app ever written. Lucky.
Or that I am so good with the camera that I don't need much help on the computer
Most people who praise LR talk about its ability as a DAM when compared to say C1 Pro which most objective reviews argue is better at adjustments and RAW processing. I don't need all that DAM power. Keywords and dates and smart albums work for me. To be fair, I only have 30K photos or so that I keep.
And if you think Photos is the worst photography app ever written, you're the lucky one. There are some real painful ones out there. But, we already know that you don't know anything about Photos, never really tried it, and are just repeating what you heard someone else complain about and even then it was made up. This is evidenced by you not knowing about right-click copy adjustments (which, incidentally is a method you use in Lightroom as well). If you'd done more that notice it wasn't Lightroom before dismissing it, you would know these things.
I TRIED Lightroom, C1 Pro, Aperture, DarkTable, and a few others whose names escape me. I went with Lightroom for several months based on the LR/Photoshop > C1Pro alone at the same $10 a month price tag. I discovered it was getting in the way of my workflow and life more than it was helping. It was easier to get a processed image from Photos (anywhere) to send to friends, family, or clients than it was to export from LR to <rest of my world>, for example.
