> Expiring domains is bad for the web

Short-term, it might seem like it would make sense for domain registrations to be permanent, but long-term, it introduces at least two insurmountable problems:

1. Unless some other cleanup mechanism is in place, eventually (like, hundreds of years into the future) domains will need to get longer and longer as people who owned old ones disappear and new people need new ones.

2. The infrastructure costs (while nominal) to keep existing domains functioning would not be sustainable in perpetuity without relying on the assumption of more and more domains always being sold.
