Taxing capital and labor creates deadweight loss and disincentivizes investment in the production of more goods and services. Capital goods are durable goods which go to wherever they are best treated, including overseas.
If you want to tax the rich without taxing capital or labor, then you want to tax land. Unlike capital, there is only a finite supply of land and it cannot be moved overseas. Wealthy individuals like owning land in areas with high land values in stable countries with high public spending, and with a land value tax they directly pay for it.
