I completely agree with you, well said. I don't believe that the majority of coins will succeed either and there's no need to do a deep dive on most of them. I just happened to find a few of them quite interesting and this one got me thinking ... 'is this possible?'
Again, the way you approach it is very similar to myself. I think that on a surface level people may think that a sex token would be successful just because of... sex. It's a powerful advertising tool, so people with dollar signs in their eyes may believe in this type of project.
