Dude, you are just completely making shit up, and it makes no sense.

So what if Celsius and Kelvin have different 0 points - they are still valid scales and you can talk about differences between 2 measurements.

According to your logic it would be impossible to state that two Fahrenheit measurements differ by some number of degrees F - why, I have no idea.

I'm not entirely sure what point you are trying to make, but this is absolutely false from a scientific perspective.

If you believe otherwise, please provide some citations to your beliefs so we can understand what you are trying to say.
