What Cobbett would make of National Anarchism and similar currents it is impossible to say, but we National Anarchists and other radical nationalists surely share much of his views, even if his world and ours are so different. Cobbett's patriotic radicalism is not so different from our own nor his love of his people, but not what was happening to them. His dislike of increasing industrialism and urbanisation is one I believe most National Anarchists concur with too. His advocacy of the cottage economy and self-sufficiency, together his opposition to 'big' capitalism in favour of the small producer and tradesman can certainly be aligned with the distributist ideas that came after him and still influences radical nationalism today.
Cobbett's 250th birthday is a good excuse to revisit his ideas have them inspire national radicals today.
