A picture was posted where it was visible. Therefore your argument that it is never visible is incorrect.
Honestly, in the picture you posted I could not see a thing related to Santa Cruz, only the mountains behind it. You claim a thin brighter pixel line of Santa Cruz's Beach is visible. Sorry, I don't think this claim convinces anyone.
Besides that, if Santa Cruz was indeed visible in the picture you posted, your claim would still be invalid, because Santa Cruz is not always visible. And your argument is as incorrect as mine.
I have lived in Chicago for two months in 2016, and I traveled around the region. I could not believe my eyes when I clearly saw the city's skyscrapers from the opposite lake shore, in Michigan City, more than 50 miles away! That's actually the day I discovered some people still believes the Earth is flat.
The sight of Chicago's buildings from there is so rare, that pictures of the phenomenon was shown in local news broadcast.
Unfortunately, I couldn't see a grasp of Chicago the other two days I stayed in Indiana/Michigan. So, the fact I saw Chicago once more than 50 miles away rising above Lake Michigan, proves that the Earth is flat?
By the way, you can google for images of the phenomenon. I saw it with my bare eyes, but the picture I took with my phone shows only water.
