Other people have different views/experiences on this, which they're perfectly entitled to have, where names are perhaps a more fluid part of identity, connecting people with close parts of their family of origin or to a particular partner or to their family of choice and the bit of family they are most connected with changes over time. Other people use different names in different parts of their lives - a name for work and a name for home. I suspect there's considerable influence on some people's choices by institutionalised sexism, but you don't deal with that by removing or discouraging particular choices.
My main complaint here is not what people choose to call themselves in different times/different places, it's that systems/structures are not in place to reflect what people are choosing to do in terms of names. With some obvious exceptions, most of the time people who have altered their names want to be findable by both old and new name (or both home name and work name) or by a number of different names all at the same time and social media is not geared up for this. It expects people to have one name only. The same is true of things like passports (GB driving licences at least provide space on the paper counterpart for alternative signatures) - why can't passports and driving licences show someone's current preferred name and then give a list of previous names/also current names?
A lot of the problems that come with changing names (think serious professional ones, like publication records for academics and more mundane ones, like trying to cash a cheque addressed in the wrong name, the administration and paperwork involved in changing your name) primarily affect women, because it tends to be more women than men who alter their names could be avoided if we set up systems to explicitly recognise that Mrs Bloggs is also Miss Jones and that Miss Jones is still one of her names, even if she now prefers to be addressed as Mrs Bloggs, so colleagues, at the level of acquaintances she's not dealt with for some years can still find her on LinkedIn and she can cash cheques made payable to either name. Systems are easier to alter than human behaviour, so why not adapt systems that work better for current trends?
