I think anyone who
wants to defy the regulations could do so

I'm a real rebel too (tell me not to do something and just watch me go

)
BUT although they may seem daft, too much hassle, too expensive to stick to, a pointless waste of time just to keep folks in government jobs (in some, but not all cases)

they are there for a reason. To keep us free from disease outbreaks (UK has big import/export markets that would be financially damaged by this) and to protect the public who buy and eat the pork produced.
In terms of penalties - I'm sure they could slap a major fine, a ban from keeping animals and I suppose they could (in theory) throw you in jail, but for me sticking to the regulations and best practice guidelines lets me get the absolute best from my pigs and minimises the chances of me being responsible for the next disease outbreak. I wouldn't want that to be my fault.
