The reason no one could answer cleanly is that both sides give you flags instead of mechanisms. "They sacrificed decentralization" vs "Satoshi's vision" — neither tells you *how* anything actually works.

Here's the mechanism in one sentence: **BTC chose a 1MB block cap and disabled a set of opcodes.** Those were choices made later, not part of the original design. Everything cascades from there. If your L1 can only carry a small, restricted payload, L2 isn't a feature — it's an escape hatch. Lightning, rollups, sidechains exist because the base layer was deliberately constrained.

BSV simply didn't make those constraints. Unbounded blocks, original scripting restored. So L1 can hold arbitrary data and arbitrary contracts at arbitrary size. There's nothing that *needs* to move to a second layer because the first layer already works.

You know this one in your body. You left BTC Ordinals because photo quality had to be degraded to fit. That wasn't physics — that was a decision you bumped into. Arweave gave you the capacity back. BSV's answer is that the base chain should have had that capacity from the start.

The scaling piece (UTXO parallelism — non-overlapping transactions validate independently, so throughput grows with bandwidth and compute) falls out of the same idea: don't fight three properties for a fixed-size block, let one of them expand with hardware.

That's the physics. Everything you listed — L1 completion, large capacity, low cost, fast tx — comes out of *those* choices, not out of a tradeoff against decentralization.

And I think the reason something still doesn't quite sit right is the hardest part: you've been reading blockchain inside the BTC/ETH framing for years, and that framing insists the trilemma *is* physics. It isn't. It's a shape that emerges from specific design choices. The unease is the framing letting go — uncomfortable precisely because the old axes felt like gravity and now they look like a map.
