I would rather be at the pool with a drink in hand or on a boat if the alternative is watching some jackass that hit a 3 wood 280 that one time 6 years ago with a 20 mph wind at his back wait for the green to clear on a par 5 while he's sitting 290 out. Also rather be at the pool or on the boat if the alternative is watching a bunch of hackers on their way to shooting in the mid to high 90's get everybody in their group to read a put from both sides of the hole. But slow play doesn't seem to be limited to bad golfers. I see lots of decent to good golfers play just painfully slow. If you're in a tournament, whatever. But if you are betting so much money that you feel the need to spend 3 minutes reading a putt, that means you're betting too much for your bankroll and you're a jackass. But also just generally, while the golf courses I normally play are nice, lots of the worst ones for pace of play aren't anything special as far as views. They are nice golf courses weaving through a housing development and it's not some picturesque view that much better than what you'd get at a local park.
But also it's just about being able to do something else on the day besides golf. I usually have something to do on the weekends that needs to get done, whether it's for kids or taking care of something around the house or work. If people play 4 hour rounds, I can get to the course by 8 and stick around for lunch and still have most of the afternoon to do things. A 5 hour round means even if you get there early, you're still halfway into the afternoon by the time you finish lunch. Plus that extra hour usually has you baking in the hottest part of the day, so you're actually tired when you get done, just from the oppressive heat. And for no good reason. There's just no reason to take more than 4 hours to play a round of golf if you're not in a serious professional tournament.
I will say a huge part of it is the golf courses' fault. I've seen some do 7 minute intervals for tee times, so of course those are bad. But reasonable tee times don't really fix the issue either because of slow golfers.
