You're right, a non-mining node still enforces the consensus rules. A non-mining node will reject any invalid blocks. Even if I controlled 100% of the mining hashrate I could not create a block that did something to violate the consensus rules. For example I couldn't mine a block that resulted in >21MM bitcoins.

In fact, with Bitcoin Cash you can basically see what happens if blocks are created according to different rules. However I image if suddenl 100% of the miners decided 42MM bitcoins is better (because 42), something a lot of users would be opposed to (printing money), things would become 'interesting'.
