I will give you two answers for why this is, one simple and the other rather involved.
The simple answer: quantum statistics are only relevant for truly indistinguishable objects. Fundamental particles and simple composites (like atoms or some molecules) can be indistinguishable in this way, but a macroscopic object is so complex that there is a vanishing chance of two being identical. So no identical objects means no Bose condensation (that is, no macroscopic occupation of the same state).
The longer answer: you've been lied to about what exactly a Bose condensation really is. The closest system we have to an ideal Bose condensate is in a trapped ultracold gas, of the type that won the 1997 Nobel prize. In these systems all the atoms have the same probability distribution for their locations, and one can see macroscopic coherence effects like interference between two clouds. But the atoms are not in the exact same place, in the sense that if you made a very precise measurement of all the atomic positions at the same time you would find that no two are overlapping.
What's going on here? There are two important length scales in a quantum atom: the distance between the electrons and nucleus (usually less than 1 nm), and the space over which the total wavefunction of the atom itself is distributed, which must be at least as large but has no upper limit. For example, in these ultracold gases, the wavefunctions might be about 100,000 times larger than the electronic radius. Both of these are, in some sense, the "size" of the atom.
Bose condensation of atoms is only a sensible notion when the size of the wavefunction is much larger than the electronic radius. What happens, really, is that on the scale of the wavefunction each of the atoms has approximately the same distribution of possible positions, but this approximation (and it is an approximation) would break down if you confined the atoms' wavefunctions to not much larger than the electronic radius. At that point, you can no longer treat the atoms as point-like effective bosons, and must instead study the system in terms of their internal structures.
Macroscopic objects, on the other hand, never have any significant delocalization of their wavefunctions, which is why we think of things as having a definite position. It would take some time to explain why this is, but it is due to a phenomenon known as decoherence that you can look around for more information about. As a result, it is impossible for two macroscopic objects to overlap in their wavefunctions while having their internal structures be well-separated. And, of course, as CuriousOne says the internal structure of matter features Pauli exclusion and electrostatic interactions when things get too close. So even if you had two truly identical bosonic stones, you would never be able to delocalize them enough for their wavefunctions to overlap without their internal structures being near each other.
