I tried going in deep enough to replace my water pump preventively. But I got stuck early as I just could not get this stupid can gear off. It’s like it’s welded on. I found a puller that fits at a local shop but the teeth on it just bend. I’m not sure more force is really going to help preserve the gear as the puller started deform the edge of the gear. I watched YouTube videos of this step and they all seem to pop off easily. What’s next? Cutting it off?

I'd order a replacement gear and keep going with the puller.
Load the puller up with some tension, and use a hammer or hammer and a drift to tap the gear to shake it loose.
If you can see physical damage on the gear, it's already toast and should not be reused

Do not sweat on keeping that gear

It runs true and the belt doesn't ride anywhere close to the edge so I buttoned it all back up. I usually order parts from Amayama since I'm in Japan and it says the pulley has a lead time of 17-42 days! I'm going to order it.. but since I'm going on a trip for two months in October I might even drop this thing off at the dealer asking them to change the water pump.. knowing that they will have to get past this mini boss on the way

Big gamble.
You say there's physical damage to the gear. If the belt runs off or is damaged and breaks, you'll have a bunch of paperweights in a car iron case

Finally got past the gear today. I tried a lot of other tricks including heating it to 250* C and using a hose clamp around the puller arms to keep it from popping off the gear. This only allowed me to break the puller.
With a new gear, woodruff key, seal, and water pump in my possession, I stopped playing nice and just started cutting it off above the keyway with a large dental dam of plastic sheet to protect the motor from grinder swarf. Eventually it cracked at the keyway and slid right off. There was no loctite.. it was simply over torqued by the hack who last replaced the water pump. That person also didn't do a great job sealing the timing cover, leading to a build up of dirt on the front of the engine. I've finally got it cleaned up and feel so relieved that problem is behind me
