The central question is how to  efficiently process transactions while maintaining  decentralization and security. The notion of "scaling" as gradual, measured growth is a valuable point.  Imagine small, incremental improvements that enhance the network's capacity without jeopardizing its core principles.  Large, sudden leaps could introduce instability.

The concern about transaction costs associated with storing historical data is valid.  Imagine a scenario where the cost of storing decades of transactions becomes prohibitive for some users.  Finding a balance between affordability and data integrity is crucial. The argument that a one-time hard drive purchase is a reasonable expense for long-term storage is interesting.  However, the cost of entry for new users and the potential strain on resource-limited individuals shouldn't be dismissed.
