As long as the productivity stays the same or increased, this option is viable. But if not, it isn't. Increased productivity from shorter hours is good, of course, but Keynes thought that even decreased productivity could be fine, as at some point it will be "enough". Here's the catch: under competitive market economy, there is never "enough". And if you pass on market economy in your country, there are other countries who will outcompete you, both economically and militarily.
