What? Are you arguing that because a phobia (that not everyone had) exists, beauty is not subjective but absolute? I'd love to see how you measure beauty if so, including the "beauty of code".

Trypophobia proves beauty subjective, not the other way around. I can find an image beautiful that someone with trypophobia finds deeply unsettling.

Objective / subjective does not mean that things cannot be experienced relatively. Someone colourblind isn't able to distinguish all colours, yet it does not mean that colours as a frequency of electromagnetic radiation are subjective, only their experience is.
