Hello.
I am afraid there's really no other way to go about this. As an activity, Livid Farm is extremely click intensive and requires a lot of attention in order to earn the points. After a while, you'll become used to identifying and curing the various plants. -shudders-
I wouldn't really recommend world-hopping at the farm. Just stick with the world that you're on, and complete the tasks when they reset themselves. Use free time to make additional fence pannels, bunch produce, or even work on protean materials.
One way of increasing your points is by using a Livid Farm point enhancer. You can randomly find these from the Motherlode Maw in Prifddinas, receive them from Wythien, or from Meg's questions at the Quest Caravan (if you have the Adventurer in training perk). Alternatively, you can convert an unfocused reward enhancer into a Livid Farm points enhancer. These items do have a limited charge, but they'll help boost your points as you work on the farm. I'd recommend checking with Wythien in Prifddinas, to see if you have any that you can use.
You are correct in saying that the traveling merchant offers a large number of points. This is something that would be awarded in the form of a livid plant, which can also be earned by completing Pauline Polaris's requests at Manor Farm, in Ardougne. Both of these are random, and I wouldn't recommend fully relying on them.
From a personal perspective, I found setting myself a target of 20k points a day helped me work through it. Use enhancers if you have them, remember to do the random events, and try to buy the livid plant from the merchant when it's available.
I hope that helps.
