Why is "Automated payment transaction tax" trending?

Wikipedia Overview

The Automated Payment Transaction (APT) tax is a small, uniform tax on all economic transactions, which would involve simplification, base broadening, reductions in marginal tax rates, the elimination of tax and information returns and the automatic collection of tax revenues at the payment source. This proposal is to replace all United States taxes with a single tax on every transaction in the economy. The APT approach would extend the tax base from income, consumption and wealth to all transactions. Proponents regard it as a revenue neutral transactions tax, whose tax base is primarily made up of financial transactions. It is based on the fundamental view of taxation as a "public brokerage fee accessed by the government to pay for the provision of the monetary, legal and political institutions that protect private property rights and facilitate market trade and commerce." The APT tax extends the tax reform ideas of John Maynard Keynes, James Tobin and Lawrence Summers, to their logical conclusion, namely to tax the broadest possible tax base at the lowest possible tax rate. The goal is to significantly improve economic efficiency, enhance stability in financial markets, and reduce to a minimum the costs of tax administration.
