Larger blocks cause propagation delays. This increases orphaning rates, which disproportionately hurts smaller miners and will eventually force them off the network via unprofitability. Miners can sidestep these problems by centralizing -- pooling hashpower, colocation. Less mining entities, each with larger market share = bigger threat of transaction censorship, government targeting of miners, 51%/selfish mining attacks, political hard fork attacks, etc.

Larger blocks also cause increased bandwidth requirements. Data upload limitations are the primary bottleneck here. People who don't have access to unlimited internet data will become increasingly likely to shut down their nodes as it begins to interfere with streaming, gaming, file sharing, etc. The less full nodes there are, the easier the consensus is to attack.

What's the largest contributing factor to increased propagation delay? Is it transaction verification, a bandwidth issue, maybe something else? Verifying more transactions would slow down block creation, but I don't think it would by too much. As for bandwidth, miners don't send out blocks to every node, they send them to their peers who then propagate them further, so I'm not quite sure I understand how bandwidth is a problem since there are plenty of nodes transmitting and receiving data.

block size does not harm decentralization, how block size is increased can do that. for example if you increase it suddenly to a much bigger number now it will end up centralizing bitcoin but if it is increased slowly with the advancement of hardware and internet speed then it can't do much harm.

Without inflation, the system needs fee revenue to continue incentivizing miners. The block size limit is the only means we have to enforce scarcity of block space, which guarantees fee revenue. Otherwise, Bitcoin's Byzantine fault tolerance may be threatened as block rewards decline in value. You can't have a network worth many billions or trillions of USD where miners have no incentive to secure the network.

Agreed, but why would users want to pay massive fees to cover the miners expenses, especially if they can use other networks for far cheaper (I know I know "they get a secure decentralized network" but still, does this limit the types of transactions that will be capable on the bitcoin network? Is this where LN comes in?). Is it fair to assume that up til now (and maybe for a few more years) miners have been taking the hit in terms of fees with the belief that their accumulated BTC will be worth more in the future than their current mining operation has cost them (i.e a net positive in the future)?

Ironically here i am, weeks into syncing the blockchain and run a full node, but I'm barely halfway there (84g). I like bitcoin core solution, and the market likes bitcoin core as well regardless of what fork supporters say.

I installed core and was downloading the blockchain a few months ago on my laptop to try to use JSON-RPC with a python/bitcoin library, I had no idea it was over 200GB and eventually while bitcoind was getting blocks and verifying transactions I got a message saying my laptop was out of space Tongue

On top of that I didn't have an internet connection at my place so I was downloading it at Starbucks and stuff so it took a couple weeks to get that far, yet it only took a few seconds to delete nearly the whole blockchain Cry

I felt so stupid when I realized I didn't check how much storage my SSD had...
