No. It's because farmers sometimes pollute rivers (despite household sewage being pumped into UK rivers daily), want to kill badgers to stop TB spreading, and because they work large areas of land they're obviously wealthy.
Dyson? Sure - he seems performative (from afar, I'm antipodean to this BTW) with his industrialised strawberry wheels etc.

Lost me .. I'm sure the UK has a few gumbooted millionaire class rockers / composers - I'm guessing that's a throw at the impresario of musical theatre with a life peerage who is rarely seen cutting hay.
I'm not sure I'd class either of those as farmers (by our local understanding), and Clarkson smacks of content farmer cos player more than generationally consistent production farmer .. but perhaps he might get there.
Andrew Lloyd Webber. Billionaire composer of musicals like cats and phantom. Also a farmer apparently, owning thousands of acres and befitting from the tax breaks and hope value.
They either employ people to farm the land (like Clarkson did I to 2019, and indeed stop does), or rent the land out for a tiny return on investment in the 1-2% range while avoiding the only tax that even attempts to fight against the aristocracy
