I think to some degree there's usefulness in gatekeeping titles - as titles could be a great way to know areas or level of expertise. Key word "could" be.

Unfortunately the nature of language combined with personally assigned titles means that there's no point in even trying because, i think, it's impossible. Call yourself whatever you want. I'm still going to need to vet it for myself if i need to hire you.

titles are often just a way to make an employee feel self important without giving them a raise. see pmarca and zuck discussing this.
