Can you link to some sources about that? No issue, I only think the contrast between your post and for example @ranochigo's is quite notable 
I don't consider those points as it doesn't answer the topic so it is quite a different evaluation. I'm also refraining from analyzing what conforms to the Bitcoin's values because it can be rather subjective and is likely not the focus for most Bitcoin users.By the way, I wonder if a service exists which lets you query a full node freely on a web interface, i.e. where you can download chunks of blocks instead of querying addresses, and then search the data offline for e.g. transactions and addresses. I guess some block explorers may allow that via API but a web interface would be nice for "quick and fast" queries.
You can't download the chunks of blocks since they would be meaningless without having the blocks before it. It would also be the best practice to validate all the blocks as well. To query transactions like a blockexplorer, you need to index all of the transactions, which is not what Bitcoin Core or any other full node does by default.Otherwise, mempool.space would be a pretty nice solution for a self-hosted explorer.
