All of that is agreeable, I'm just saying that if anyone disputed me getting free relief I just wouldn't take the relief and get on with it as that's easier.I think this is an important principle, so let me try and present it as clearly as I can.
1. If you aren't in competition you can do what you like, how you like it - the end.
2. If you are in competition the rules are there to enable you to compete either against opponents, or against the field. In the former situation, match play, what you agree with your opponents is fine until you don't agree - at which point you have a choice; do what you believe the rules permit, and risk them making a claim that you were in breach of the rules which then has to be ruled on by the committee, or agree with their view.
In a stroke play event if your marker doesn't agree with what you did he will refuse to sign your card (so it's good to discuss it with him at the time to avoid later hassle) and if your fellow competitors don't agree they must raise it with the committee (so again it is sensible to gauge opinion at the time - but unlike match play consensus doesn't make what was done correct).
In this particular situation the correct procedure if you believe you are entitled to relief, but your marker or others disagree, is to proceed under 20.1 c (which incidentially starts with the line "no right to decide rules issues by agreement"). Note this is fundamentally different from you making a decision and no body having any issues with it - the point I think Liverpool Phil was making.
