What of previous generations of HBM? Older consumer AMD GPUs (Vega) and Titan V had HBM2. According to https://en.wikipedia.org/wiki/Radeon_RX_Vega_series#Radeon_V... you could get 16GB with 1TB/s for $700 at release. It is no longer use in data centers. I'd gladly pay $2800 for 48GB with 4TB/s.

Previous generation of HBM is not any cheaper than the current ones, and it is no longer in production, the lines having shifted to the new stuff.

HBM2 is still in volume production. New products coming out with it on the ASIC side. Gaudi 3 uses HBM2e.
