As others have said, the solution is not to sit out but to learn to play well in a situation, where chip preservation is more important than chip accumulation. You talk about getting jammed on by short stacks, and there are plenty of situations, where its totally fine to bet and then fold to a jam. As a big stack its not your obligation to bust people or be the table sherif.
Also you are not *always* going to lose flips, and perhaps you just have a tendency to overly focus on the negative outcomes and forget the positive ones. Yes it sucks to have a big stack, when late registration closes, and then still not make it in the money. But if you play well, there will also be times, where you use this phase of the tournament to increase your stack further, and sitting out only to limp into the money with a crippled stack is definitely not the solution.
