As if that is always possible. You would need to build a big enclosure padded out with cotton wool. Many dangers in the real world, you can maybe stop the kid touching an oven, but you won't be always there to stop him/her from dangerous situations.
Were your responding to 'make it physically impossible for the child to access a hot oven.'?
If yes, then you're wrong: its (99%) always possible. Just buy and install a kid's barrier and park the 2yo in his room during the cooking. Or use a cold door oven. No need for a 'big enclosure padded out with cotton wool'.

100% agree, unfortunately. My point was that, agreeing with the parent (no pun intended), at 2yo, you don't loose sight on your child if it's environment is not 100% safe, end of the discussion.
