Note, Arweave offers '200 years or as long as the endowment allows' for their funding model for storage. Their endowment is AR tokens, which they print themselves, from nothing. Payment for storage goes back into their endowment.
The tokens are a one time payment for storage, so users are less likely to need them over time.
Every time I read about Arweave I cannot understand how it can work sustainably, and a 200 year storage project -- while ambitious -- cannot live on shittokens alone.
