I think you fundamentally misunderstand Bitcoin. People don't pay to store data on the blockchain; they pay to get their transactions mined. There's no guarantee that all the blocks of the Bitcoin blockchain will stick around forever, only that there'll be a consensus as to what the current block is, and what the states of all the wallets are (since that's the only information you need to validate a new block). Keeping historical blocks around is not a property of Bitcoin. No up-front blockchain payment system can keep data around for any length of time. (There is no mechanism enforcing the storage of the data; such a mechanism cannot exist within a computer system.) “$10/GB for 200 years” are the words of a snake-oil salesperson – or, more charitably, somebody who hasn't properly read the marketing copy.

You are confusing function and implementation. Technically "get their transactions mined" is having a piece of data written to the chain. You are correct that in Bitcoin there is less incentive to store old blocks. But in chains crafted to store data for a long time there is. I am stopping this discussion here because you are too negative (almost aggressive) for my liking. But it will be an interesting thread to read again in 20 years when all this has played out.
