> Given enough time, any valuable asset's distribution will be heavily concentrated in the hands of the rich.

That reads like a tautology—they're called "the rich" because they have wealth, so naturally if you look at the distribution of assets most will be in the hands of the rich. One doesn't accumulate assets purely by being rich, however, as many a lottery winner can attest. Barring the occasional (and usually short-lived) windfall, for the most part those who attain wealth do so because they possess certain habits and preferences related to saving and investing. Even if you reset the distribution of wealth those tendencies would remain and bring about a gradual return to the original economic structure.
