This is simply an ordinal scale, to which we are going to allocate arbitrary numbers. The difference between ugly point one and ugly point two is subjective.

Mean is hugely flawed in this context (reporting a 95% confidence interval would be even more ridiculous).

How is it useful in this situation to report a mean of, for example, 3.7 (95% CI 2.6-4.2)? It is meaningless.

Median (interquartile range) is still flawed, but gives you an overview of the data without making assumptions about the importance of the interval between data points.
