I am in a fairly urban area in one of the fastest developing countries of the world where we have good enough internet data capacity and speed to watch a few episodes on Netflix every second day. Yet, it is nowhere near the almost 200 GB plus upload/ download that a Bitcoin full node needs right now.
Any talk of increasing blocksize should first consider the actual internet availability. Only the most affluent of cities have those kind of limits.
Even if better internet reaches everywhere, you still won't solve the issue of Bitcoin being resource intensive. Already, we have calculations about how Bitcoin electricity consumption is equivalent to some Scandinavian country's consumption. Next it'll be about data and how much of it is being consumed by Blockchain ledgers, especially Bitcoin.
From Bitcoin’s viewpoint, does it need to be “solved”? I believe the people who say that it’s “a problem”, don’t truly understand Bitcoin. Or try not to understand that there’s more to Bitcoin, and more to its implications on Banking and Finance’s current condition, than what we see. Maybe energy companies could become the new foundation from which sound, hard money is produced and issued.
