>In any kind of non-uniform distribution of any good

Not in any kind. It is absolutely the case, if there's mostly untaxed generational wealth transfer. Imagine this - you are born in this world with nothing. And every parcel of land and property is owned by somebody - somebody who with high likelihood inherited it or hundreds of millions or billions of assets on spawn.

Now obviously, you can inherit all sorts of other factors too - like very valuable social networks and a set of trade skills carefully passed down and tought. But even neglecting those, the largely untaxed generational wealth transfer would naturally lead to massive inequalities and disproportionate amounts of wealth concentrated in few families.
