For years I thought that Doug McIlroy had a very odd name, until I watched some presentation on YouTube and first heard his name being pronounced – "ah, so that's an i and not a double L!"
It probably doesn't help much that both Lain and Lan are fairly famous fictional characters now (Serial Experiments Lain and al'Lan Mandragoran from Wheel of Time).
Funny story, I was named "Steven" and yet I've been called Steve my whole life, at my preference.
Recently I went through the process of changing my name legally, because I'd fallen into a bad habit of writing "Steve" when asked for my name on some documents, but then remembering my "official" name was "Steven" on others.
Having multiple IDs with different names, especially after moving to a new country, was just too much of a pain - for example my official residence permit name didn't match my passport name, which caused some fun at airports.
The first thing gifted was life, and though that was not bestowed with consent, it's one thing I'd argue for retaining as long as possible. Everything else is fair game to discard in service of making that life a good one.
The world has almost unanimously decided my name is now Lain.
