oh yes, I'm sure you know all about the hurdles of validating incoming blocks. 

let's suppose every segwit floppy disk is half filled with runestone shitcoin creation and the other half is for lightning channel maintenance, and bitcoin gets really really popular. what happens to the cost of owning a UTXO or opening a lightning channel, and where does that force most of the users in the world to go? they go to fucking cash app. they don't have control over their funds. they are shoved into a CENTRALIZED CUSTODIAN. the cost of maintaining a lightning channel will be greater than the cost of a non-mining node that meets the minimum requirements for being an OP_RETURN shitcoin calculator. you are making it really easy to set up a worthless non-mining node so you can make it really hard to not be in a centralized custodian. you're not protecting decentralization.
