I'll tell you what my broker told me about insurance surveys. He told me the insurance company may not even look at the survey. It goes in your file, and they write the policy. If/when you file a claim, then the survey gets read very closely, and coverage is denied for any issue whose cause is related to an uncorrected survey problem.
So if you are truly confident that the issues in the survey would not cause an insurance claim, you are free to ignore them. You still have coverage for anything unrelated to survey issues.
So it's entirely up to you. Nobody is stopping you from sailing now. You just won't be covered if those trivial issues cause an insurance claim.
Take my advice with a grain of salt, because free advice is worth what you paid for it, and sometimes less.
