In this speculative scenario, robots could do that, but they can't just do it anywhere as it depends on where the minerals and land is at and who owns it, where power plants can be built, how supplies get shipped.
The idea that economics goes out the windows in a post-AGI world is highly speculative and not a situation that has ever happened in the real world.
I did not say economics goes out of the window, I said monetary economics.
With cheap robotic labor, many resource mines that are currently not economically viable will become viable, so basic resources will become much more plentiful.
The new economics will probably be based on needed energy, direct tally of needed material resources, or the number of robot-hours something takes to do.

Land is an inherently limited resource, so some kind of money might still exist for that, even after the singularity. The point is: whatever process exists to obtain land after the singularity, the robots can do it.

Who's robots? Who will get all this land? And its spoils, and the robots that multiply them?
Because your utopia sounds like a recipe for making our oligarchs even more powerful at the expense of the rest of us. It sounds like a slide into neofeudalism. The already existing don't even need labor to multiply their riches anymore, the rest of us will be robbed of being able to trade our labor for even basic subsistence.
You are missing the point: robotic labor does not create anything "at the expense of the rest of us". It's not some stock market speculation, but real productivity increase. The pie of wealth is not fixed, the robots actually enlarge it, massively. The robot owning class wil not be some exclusive billionaire club: as the price of robots comes down (inevitable, with any technology, doubly so with one that can make itself), essentially everyone will own one, just like almost everyone owns a car today (or could own one if they needed it).
Worst case scenario: you will live exactly as you live today, with one change: instead of you having to do your job, your robot will do it for you, and you gain more free time.
You've already conceded that there is inherently limited resources like land. These are going to be the limiting factor in any economic system, the key question is always how you distribute these.
Robots will not magically produce more land. What they will do is that the ones with the capital to buy many robots will be able to use those robots to then buy up all the land and then extract the resources from there to build even more robots etc.
No resources for you and me. No robots for us either. Why are you talking about prices going down? We're making money obsolete, remember? Why would they even sell us robots when they already own all the land and all the resources to make as many robots as they want? Sure, the pie will get bigger. But you ain't getting a slice.
What leverage would the vast majority of people have? If the oligarchs own all the robots and land and resources, how do we even ensure basic subsistence? Our labor is worthless. Our money is worthless. What stops them from... simply not sharing? The goodness of their hearts?
They can also perform work with the aim to earn money to buy more land.
