I fail to see what is so fascinating about my parcel that anyone would wish to come onto it. I do not begrudge people using the road, and I do agree the system needs improving so they can drive on it without hitting ban lines or no warning security orbs. Some have tried saying go rent private land. I was doing this before, and it is far more expensive. My current parcel on mainland is more then twice the size of the one I had been renting and is costing me LESS per month. I really do not think it is unreasonable to expect some privacy on (virtual) land that I am paying monthly to be able to use, so yeah, I think that entitles me to decide who is allowed on my property. If I wanted to share my builds and such with others I would sell them on MP. If you want to have safer travel for driving and flying (no water on my property so sailing does not apply here) that is fine. I got no issue with you needing time to pass through or over. But do not expect me to open my entire parcel for you to freely explore and do as you wish on.
Oh, and I got more random visits on the private rental property then you would think. Was why I started using security orbs and limited access to begin with. It is sad that I actually did have to start doing this. Had at least three people that came onto my rental property and proceeded to start using my furniture and wander through my house. All three refused to leave when asked, then proceeded to get nasty with me when I ejected and banned them. So far have not had a similar issue on Mainland, but until recently I was keeping it set to limited access with ban lines. So I will see how the security orb option works (and yes I have mine set to 30 seconds warning, plenty of time to leave before being ejected.)
