>There is plenty of DDR5, its not even very expensive,

My 2x16GB of DDR5-6000 that I bought for 250€ is now 650€. 2x32GB that cost 200€ last July now goes for close to 1250€. Even my shitty ass DDR4-3000 sticks from over ten years ago would be selling for close to 300€.

DDR5 is horribly expensive, the only variants that are not as expensive are low frequencies or low amounts.
