the problem is the stocks of other domains people are collecting since 1995, you can get addicted lol

because of that difficult to argue with these guys, they will start believing after the end of the stock or after price normalization, there is no other way, so other domainers and especially SEO specialists and namers are needed that will definitely make things clear.
ok , another comparison, from historical point of view, it's like you own shops in Elyseum fields in Paris ( as a respected French domainer said ) ...
but we can say that there are other places in Paris for business, like 'La Defence' and with built in metro station and other Skyscrapper that will be built next years and will drive businesses and customers there,
also the scyscrapper or the megashops of 'La Defence' are way bigger than 1 floor 100 metres Elyseum shops.... and traffic is good also.
the problem is people are waiting, they wait for bizzare behaviour of nnnnx domains, , then second historical tld, then 3rd, then jump to national ngtld of the country that is driving the market, then others... some will try to buy the whole zone with numbers..... it's ok, no problem but in this case you fullfill only one function of the domain 'the collectionning' , but you can't use it for commercial purposes or marketing ..
