I don't really see a problem with either of your "devil's advocate" positions. Especially the patent one. Given where you're posting, I have no idea why you'd think that would be a "devil's advocate" idea.
A wealth tax is an interesting idea. I have to wonder why it's so uncommon. I'd guess it's some combination of being hard to enforce and easy to move money around. Such a tax would trigger a flight of capital, something that can't happen with a tax on houses. And you can't audit people's mattresses very easily, so it would just encourage hoarding cash.
In a world where such a tax could be enforced and applied worldwide, it doesn't seem like a terrible idea. It shouldn't be very large, but it could have similar effects to property taxes.
On the other hand, we already effectively have such a tax, we just call it "inflation" and the tax rate isn't directly controlled by the government. Inflation has the same good effects I described for property taxes, in that it discourages hoarding and encourages putting money to work. (It has bad effects to, no doubt, so this isn't a total endorsement of inflation or anything.)
Patents aren't private property. They're a government-granted temporary monopoly. In the absence of government, there's still some notion of property, but no notion whatsoever of patents.
Yes, they are. (Particularly, they are intangible personal property.)
> They're a government-granted temporary monopoly.
All "property" is government-granted monopoly in the control/use of some thing (sometimes dependent on a grant from another private party, but still ultimately government granted), concrete or abstract. Some are temporary (this is true of real and tangible personal property, too), some are permanent.

Outside of government/legality, there's certainly still some notion that things, concrete and abstract, can belong to certain people such that it is wrong to "steal" them, and that certainly includes ideas. The particular details and names of particular classes of property are, of course, products of people, over time, spending time teasing out vague notions into more detailed sets of rules -- which, in the case of property rights, is something that tends to happen in the context of government (not always by government, but you don't even have developed philosophy of property rights without government existing to create a stable enough society for people to spend time writing rather than defending their immediate personal possessions and survival necessities.)
A patent is, ultimately, a negative entity. Before a patent is granted, anybody can make certain objects or perform certain techniques. After it's filed, the patent owner's rights remain unchanged, but everybody else is restricted from doing those things.
Humans have an intrinsic idea of "property" that the legal idea is built upon. A two-year-old child understands the idea of "mine". People still own things when government is not present, they just have a harder time enforcing that ownership.
Patents, on the other hand, are an entirely governmental construct.
Thank you. I guess cash currency isn't really property either. It is backed by the "full faith and credit" of the government so it is like a IOU that the government requires you to accept to settle existing debts.
