Sad ads for failed project bikes

As I am watching local ads lately I can't help but to notice how many there are for so called project bikes. Bikes that are not running that the owner was trying to turn into a cafe racer or street bob etc. and then for some inexplicable reason just gave up halfway through. Typically the sellers are asking quite a bit of money for what is essentially a parts bike now and usually without a title.
What bugs me about it is that in many cases the bikes are very nice vintage machines, or were for that matter, and now they might never ride again.

Why do people do this? I think it's sad that so many old bikes are just being ruined by wanna-be bike builder types who get ahold of some nice vintage bike, cut the frame, put on some uncomfortable aftermarket handlebars and a slip-on and then let the bike sit and rot in non-running condition for a long time before listing it for sale at some outrageous price without a title.
For shame.

If it's the millennial Hipsters doing this then the prevalence of these ads makes some sense. Those people all expound upon that whole maker ideal but none of them seem to have the attention span required to complete any project.

I like to tinker and to that end I have my Suzuki Savage. Cheap, commonplace and dead simple to work on. I stick to light fabrications I can manage with limited tools and bolt-on stuff. For larger tasks like installing the big bore kit I take it to a qualified mechanic with the skills and tools to do it right. I keep the bike rideable, no major tear downs. And I never bite off more than I can swallow at one time.
I think there's plenty of bikes like the Savage that are commonplace and seemingly designed with modding in mind without having to rip apart nice old vintage bikes which ought to be restored and not converted into something they're not. Or cut up, spray painted and left in pieces never to ride again by people who can't follow through or simply don't have a clue to begin with.
