monero grows 8 times faster on disk than bitcoin, for the same TPS. monero is also harder to prune and can't support SPV. even your nodeless wallet has to scan every block since the wallet birthday, so it's heavy. on monero you are gambling that consumer grade hardware and internet service improve faster than the rate of adoption. maybe it will. monero adoption is mostly slow and steady. their only fallback plan is even shittier payment channels.

BTC community decided NOT to make that gamble at all, instead focusing entirely on lightning which has been a disaster, and fake sidechains, and a bunch of other stupid centralized things. everything they did was overwhelmingly centralizing. they are allergic to any expressiveness which could enable real sidechains, shielded CSV, or anything else.

with monero, maybe you will drown in excessively large blocks someday and maybe you won't. on bitcoin you are already giving up and shoving everyone into spark. both of these plans are dumb compared to real sidechains, where you can try everything and ignore anything you don't care about.
