it costs just 6 billion to destryo bitcoin with a 51% attack

Source for the 6 billion ?

Additionally one can not 'destroy' bitcoin by maintaining 51% of the hashrate for a short timespan.

this is something a commited developed country easily could affort,

Or they could just easily ban the posession/usage/trading of cryptocurrencies. Would cost them way less.
Additionally it would need a hardware manufacturer to produce all the ASIC's needed to obtain such a big % of the hashrate.

however if there is an intelligent businesman who lends a ton of money to create this haspower as some form of cyberweapon of a state, this could truly exist.

If this businessman were 'intelligent', he wouldn't 'invest' in tons of mining hardware just to NOT MAKE PROFIT with it.
If you own enough ASICS to have a big % of the total hashrate, you earn WAY MORE when simply mining.

and what makes it worse this cyber weapon would then be able to eat more and more as each destroyed cryptocurrency would make the attacker even richer, which he can invest to have even more hashpower

Thats not how it works.
ASIC's do only work for ONE algorithm. After 'destroying' bitcoin, the whole hardware would be useless and worth almost nothing anymore.
This doesn't make the attacker richer.. an attacker would effectively throw money away.

Please stop posting misleading information. All of your 'facts' are simply wrong and illogical.

51% destroyes its trust massively though and all those constand fix and foxes, will make people be pissed of and return to POS systems
