According to @stonecoldpat0, the main blocker to cheaper on-chain execution is that MEV bots immediately absorb any added blockspace, so throughput increases alone will not sustainably lower transaction fees, source: @stonecoldpat0. He states that fees were introduced primarily as a DoS and anti-spam mechanism rather than a revenue source, and even with 100x capacity, fees must remain meaningful to impose costs on bots and prevent resource abuse, source: @stonecoldpat0. He frames the binding condition as collective MEV profits versus what real users are willing to pay in fees; if MEV profits exceed user fee tolerance, congestion and elevated costs persist, source: @stonecoldpat0. Trading takeaway: plan for a non-zero fee floor and sustained MEV-driven competition during peak events; strategies dependent on ultra-cheap on-chain execution need added MEV mitigation or alternative execution routes to remain viable, source: @stonecoldpat0.
