Yeah but if all you need to keep is the UTXO set, then the blockchain doesn't really grow, it fluctuates on size, and approximates a steady state size over time. It only really grows with the size of the userbase. That's how mimblewimble worked on the original paper. With such a scheme transaction size is not really a factor, the overwhelmomg majority of the blockchain storage requirements is historical data.
