Basically this being "raw" honey, it has tons of pollen in it, so it would have massive amounts of "wild yeast".
I don't want anything living in my fermentation than teh added yeast for a controlled fermentation.
Also, while boiling sterilize the solution, it also makes some bigger proteins to flock together and allows you to get rid of it, making for a clearer (more attractive) end product.
But mianly I boil it do kill off wild yeast and bacteria.
When it comes to beer there are other reasons for boiling, bt won't go into those unless asked, I nerd out enough as it is :Spin::Spin:
I get my huge buckets of honey for free from my brew mentor, he gets loads and loads every year from neighbouring bee keepers, the parts they don't want to or can't sell for various reasons.
He gives me some now and then for free so I can brew mead or use it in beers.
If I had to pay for a huge ass bucket of honey that size my mead would become fairly expensive indeed...
Might I suggest using campden tablets (1 per gallon) crushed and mixed into the must and let to sit 24 hours before adding the yeast. That will also kill wild yeasts and bacteria without having to boil.
