Define "scaling" in Bitcoin. I believe the word is used around the forum without the proper context. Is simply increasing the transaction throughput in Bitcoin, scaling?
This^^^
If the word "scaling" is misused to mean the same thing as "throughput", it's easy to pose as a helpful person recommending throughput increases as "the" solution. The problem being, that only increasing the throughput actually hurts the strength (i.e. the decntralized nature) of the Bitcoin network, and so mysteriously helpful people are always hanging around the Bitcoin community incessantly suggesting this bad idea

@squatter gets it exactly right here:
The only ways to increase ONCHAIN Scaling for a single blockchain.
1. Increase BlockSize
2. Faster BlockSpeed
3. Compressing More Transactions into a given blocksize
The first two options only increase throughput. They don't address the system's ability to handle that throughput.
