I would be interested to see your reference - mine shows the addition for MEF is not 300' but a variable amount depending upon height of the obstacle and is in the order of 100' for a 2000' obstacle, then rounded up to the nearest 100' if not exact 100's.
I think you are getting the 300' from the fact that objects under 300' are not shown on a CAA chart, so if looking at terrain spot heights then you need to take this into account, the MEF marked does take this into account though.
You are correct that in VFR you do not need to be above MSA OR MEF, though the MSA should ideally be known in case the weather is not as forecast and you are unable to maintain VFR.
