Just to hit on this one side point, that's not quite right.

There are tradeoffs in blockchains where you CAN start at the beginning of the chain and be absolutely certain that it's all solid, but there are techniques for trimming parts of the chain to lower storage requirements, maybe with less certainty in what you know of the state of the chain.

You know how in Bitcoin there is a tradeoff between time and listening for confirmations? It's a similar thing.

You don't necessarily have to have the entire blockchain locally. That's the ideal, but there are ways to avoid it.
