It's not as simple as trusting miners, Bitcoin security needs some
reasonable portion of economic interest to be validating their receipt
of coins against a full node they run.
I do it myself because I dont want to lose money, as do many power
users. Most bitcoin ecosystem companies do it. You dont have to run
it all the time, just sync it when you want to check your own coin
receipt with higher assurance.

Even if you are willing to trust others, trusting miners or random
full nodes would be unsafe if not for the reasonable portion of
economic interest validating their own received coins. That holds
miners honest, otherwise they could more easily present fake
information to SPV users.

Bitcoin's very reason for existence is to avoid that need. For people
fully happy to trust others with their money, Bitcoin may not be as
interesting to them.

What Pieter said is an accurate summary and non-controversial.
