We do not have a railing on our wrap around deck. We had to satisfy local bylaws re the height of the deck from the ground. Insurance was never a factor.

Only your insurance agent knows for sure; ask him/her. And you should also find out the local regs; it won't matter if your insurance is willing to cover if the regs don't permit it.

However, I would not want the responsibility for paying for the probable accidents which will occur when someone falls. Kids will play without paying attention, folks will back up while talking; it's for sure that someone will be thinking about something other than where the floor ceases to be and go over the edge. Anyone who denies those obvious likelihoods, should consider carrying extra insurance. It's a safety issue, and two feet is far enough for there to be quite a bit of damage upon landing.

If there is a view worth looking at, a railing isn't going to interfere unless you make a practice of sitting on the porch floor -- and even then, there are quite attractive slim railings which would provide safety along with minimal view-blocking.

If you use black rails, they will seem to disappear when you look through them. This helps to preserve the view beyond the deck.

I've never had an insurance company care as long as you built to code. The code has rules for the drop from the finished floor to the "ground" adjacent. We terraced our back patio so that there are no railings necessary as each step down is less than that required.

Another dodge is to wrap the porch with steps all the way around. The worst you'll have then is a few extra hand rails.

The rule we used to observe was three risers: if the stairs had fewer than three, no rail was required. If the porch was not higher than 30" above grade, there was no rail required. The two do not exactly correspond. You need a stair railing at less height than you need a porch railing. Three risers is 24" maximum.

We have no railing and the drop is about 22". The insurance company never mentioned it. Code in our area would require a railing if the drop exceeded 30".

To my knowledge my insurance co. has never seen my house unless they drove by. They only wanted to know the size of it and I gave them measured drawings.

You should only be concerned about the possibility of denial of a claim if someone gets hurt and the deck is a violation of the building code or common sense, but you would use those things to guide you anyway wouldn't you?
