Vision. An artist's body of work outlives the infrastructure that hosts it. The site is mortal; the work is not. Persistence is not the immortality of any single platform — it is coordinated survivability across many mortal ones.
A working artist's website depends on a stack of payment-dependent services — domain, hosting, managed databases, CDNs. When the artist stops paying, the work disappears. The legacy is bottlenecked on a credit card. This is a design failure for anyone whose body of work matters more than their billing cycle.
