No. It's not a physical good that is subject to wear and tear. There is no excuse for a single player game to have a lifespan because it has some pointless online verification component.
Because I think it's good for software developers and consumers for people to have the flexibility to sell something that depends on online services which may become unavailable at some point in the future. This is more valuable than requiring indefinite support, public pluggable backends, or required open sourcing or backend redistribution, which imposes onerous technical or business limitations for an extremely minor consumer benefit all things considered.
