I think that natural rights impose an obligation on others to not unduly take from you one thing or another. I also think that natural rights can't be anything that obliges someone else to provide something for you. The distinction might be narrow, but it's important.
For example, the right to life imposes an obligation on others not to deprive you of that - in other words, not to kill you. But even though there are things that you need in order to remain alive (e.g., food, shelter), those are not natural rights because that would require an obligation on someone else to provide you with food and shelter.
The right to liberty imposes an obligation on others not to forcefully or fraudulently cause you to do something against your own rational judgment. However, it does not provide things like freedom from the consequences of your volitional actions.
When you consider natural rights in this way, the right to property kind of makes sense - it obliges people to not unduly deprive you of property, but it makes no obligations on others to provide you that property in the first place.
The place of government is to provide a framework that protects our natural rights with minimal imposition on those same rights - we pay taxes in order to have police and courts and such, in order to protect us from being forcefully or fraudulently being deprived of life, liberty or property. But taxes are, of course, a violation of the right to liberty because money is just a means of exchanging your work, or really your time and efforts, for someone else's time and efforts. When you're forced to provide money for a thing, it's really that you're being forced to give up your time and effort for that thing.
It's not perfect, but the point behind the concept of natural rights is to maximize the liberty of all, with the knowledge that in order to provide that liberty, you've necessarily got to impose on the very rights you intend to preserve. That's why it's extremely important to have a very minimal set of "natural" rights - every thing you declare as a "natural" right is only provided by government at the expense of another.
