I tried to not make an all inclusive statement, thus formulating it as "Tattoos as fashion", as I do recognize there are people happy with their tattoos, thus not subject to regret.

What I tried to get at, but wasn't clear about, is that tattoos serve a functional purpose (in your case it seems to partly be an identifier).

Then, specifically, tattoos with the function of fashion, is what likely leads to regret by the general laws of fashion. To quote "Project Runaway": "one day you're in, the next day you're out."
