I'm struggling to see the stupidity or violation of going surfing (assuming that it doesn't involve excessive travel to get there). Whilst surfing, you're not going to be within 2m of another person. To me, it falls into the category of enjoying nature. Obviously, there's no surf rescue service, but I believe that many surfers accept that risk all the time, surfing at beaches where it isn't available anyway. IANA surfer, BTW.
Equally, throwing frisbees at a park was labelled by Ashley Bloomfield as stupid. I don't see that... so long as the frisbee is only handled by people in your own bubble, I don't see it as more risky than walking in the park. I don't own a frisbee, BTW.
There seems to be a lowest common denominator approach, where people are being demonized for having fun, even though the activity doesn't risk spreading the virus. We're all supposed to be miserable together.
The stupidity of the above two activities is 100% obvious to any individual who is capable of looking beyond the tip of his/her nose and not just focusing on the curtailment of one's freedoms. In the event you have an accident or suffer a medical event whilst surfing, people might have to decide between saving your life (i.e. offering CPR) versus potentially exposing themselves to COVID-19. Allowing games in highly visible public areas encourage people to congregate and when caught in the moment, people's vigilance decreases and social distancing is minimised.
People are not being demonised for having fun. People are being called out for putting others at risk and limiting the efficacy of the lockdown for objectively trivial and frankly pathetic "gains" -- all in the name of asserting some kind of need when it's really all just about "Me! Me! Me!". And people like you who are mindlessly defending them are just as ridiculous and obnoxious.
