It is possible for actual value to be destroyed or lost to other people.
If you own an oil well and pay out a ton of employees to try a new extraction method which causes a fire - the actual value of your asset has been destroyed. And a lot of money has also been transferred from investors to employees. The embarrassment may also cause you to lose trust of other companies which hurts the value of future contracts. Some of the value you destroyed is gained by other companies since they can now sell their product for more - but the shareholder value of the well you own is lost.
I agree Facebook's value has a speculative element to it - but its pretty clear that the money has been lost because the thing of value has been partially destroyed both by itself and by competitors like Apple and TikTok which is stealing its revenue.
