I don’t think I understand the 12 year limit.
Personally I don’t mind hosting information related to some else’s transactions. I’ve forecasted and I run the hardware to host the whole chain for a few years. Including spam, and most people that care about Bitcoin and run a node can definitively do the same.
My point is related to the purity of Bitcoin as money, probably unachievable.
But it’s frustrating when transactions fees spike and most of the blocks data is not financial records.
