Isnt the 1k GB per year blockchain size a HUGE issue here ?
The price of storage is exponentially getting cheaper and the 1K GB would be the theoretical maximum growth.... or not going to happen for at least a few more years. Additionally, there are attempts to work on merkle tree pruning and other solutions to reduce blockchain bloat.
The reason this is important now is because their are some blocks that already are completly full at the 1MB limit. we don't want this to become the norm and have transaction fees skyrocket and confirmation times becoming 2-3 times longer.
No way regular people will buy 1-5TB drives only to run a full node out of good will. This is dreaming.
Less full nodes means a less secure network.
I don't know much about this specific problematic but put this way i'd rather have higher transaction fees than a substantially weaker network.
