The thing that stands out to me is that the OP seems pretty concerned about what other people will think about a tattoo they want. If you are unsure, and people's opinions could sway your tattoo choice, IMO, you probably should not be getting something that cannot be undone easily.
Ear piercing when unsure, fine, you can remove it, things grow back, all is good. Tattoo, when unsure, will either incur a costly removal in the future, or a lifetime of regretting the choice every time you see the tattoo in the mirror.
Bottom line, if it can't be easily undone, be damn sure that it's what you want and that you'll be happy with it no matter what anyone else thinks or says.
