That simply isn't true. Accepting a blockchain blindly without validating is the Bitcoin SPV model. In ethereum it amounts to an undiversified risk that the two mining pools needed to constitute a majority hashpower (ethermine and f2pool) will not violate the protocol, or-- if you are accepting state with few confirmations as final-- that _any_ miner will not violate the protocol.
