Then maybe I'm thinking of something else. Will have to go check in morning and get back to you. I know where I read it, just too late to go fishing

Storage, CPU, latency and bandwidth are limiting factors. In general people thought of bandwidth as the biggest limiting factor, because a real P2P node is not just receiving. Latency and CPU can be fixed through software upgrades with a huge margin. Latency (block propagation) has been fixed in BCH through I believe it's called Xthinner tech. CPU parallisation has not yet been a problem in any coin, but it essentially gives huge headroom for expansion. Storage expansion is happening as envisioned. It's much more a problem in Monero as Bitcoun can be pruned very efficiently. Back in the day some vocal people thougt or proposed that laws could break and erroring on the "safe" side seemed smart as no one can project the future. 12 years later we know new tech/ways have been discovered and laws held up. We killed MoE, because some believers beliefed the trend will break while other believers believed that this time won't be different. What do we do with this information? Personally I am happen about this, as I believe transparent blockchains to be a (at the beginnnijg neccessary) design flaw, that never should have been rising to the size they are now.
