Compare it with any "battle passes" nowadays, a dopamine-filled mechanic where you are forced to play the game, otherwise you're missing out. You are "obliged" now to play the game, otherwise you won't get all your "prizes" and get best returns. Most people burn out from these kinds of monetary systems, as they will lay down their game and won't play for a while. Your first time travel would be comparable to a purchase of this "battle pass". It felt so nice that your shop, bridge, incline is being built and that you get all of those npc events earlier, you probably will not stop after the first one.
Of course, I made a lot of assumptions, but I know who I am, and I know that if there's nothing left to do in this game, I won't be playing it anymore, 'cuz I've seen it all.
I actually think not time traveling is more like the battle passes, getting worn out thing for me. If it wasn't for quarantine, I wouldn't have time to play every day and I'd feel like I was missing out on things and super pressured to log in so I didn't. In New Leaf, I used time traveling so that when I had time, I could jump back to the day after my last play date and not miss anything--as soon as I was done with a day, I'd jump forward. Even then I still stopped playing for a long time because I was working a part-time job (teaching assistant) on top of my full time job at a startup, and I had a side hustle copyediting papers for an old boss, so I just had too much going on in my life and video games had to fall to the wayside.
Sure, some TTers jump *ahead* but not everyone who does is trying to get things faster.

What does gatekeeping mean
It's setting and maintaining (often arbitrary) rules about a community and who qualifies as belonging. Who can pass the gate and belong to the group, and who is left outside the fence/walls.
One example is how a subset of video game players will challenge women and girls on their right to call themselves gamers. They might denigrate the games the woman plays as not being "real" games because they're not "hardcore" enough. They might challenge the girl on what she knows about games to "prove" she's not a "real gamer." ("Oh, yeah, if you're such a big fan of World of Warcraft, then what's the lore behind the Lich King and what games was it established in!")
When I was in middle school, in New Jersey mind you, just outside of New York City, the Yankees were at the beginning of their 1990s dynasty. (Yeah, I'm an old, lol.) If I said I was a Yankees fan, guys would say things like "You only like the Yankees because you think Derek Jeter is hot." That's gatekeeping--it's saying I wasn't a real fan because I wasn't a fan for the "right" reasons. Meanwhile, I did not (and do not) think he's hot though he was a helluva player, and my "bona fides" as a fan would definitely have qualified me as a fan per their rules. I should not have had to to justify my liking of the Yankees with those other reasons--it should've been enough that I said "yeah, I'm a fan!" Guys might also gatekeep other guys, especially for a team like the Yankees, by calling other fans band wagoners ("you only like them because they're popular. I'm a real fan, I liked them before they were cool/good/whatever."). It's also kind of a dick move. It's fun to be a part of something like that--in 2004, I went out to Kenmore Square when the Red Sox beat the Yankees in the ALCS, since I lived two blocks away. (I actually met up with a fellow Yankees fan and we commiserated, and then we left when the police with riot gear started turning out. It was still cool to be part of such an excited, happy crowd, even if I was sad about my team's collapse.)
("Bona fides": Dad used to take me to Yankees games in the 80s/early 90s when they SUUUUUCKED. I had a Steve Sax poster on my wall. Both my parents were Yankees fans. My dad's dad and mom's dad were both Yankees fans. My mom's dad grew up in the Bronx. He used to sneak into Yankee Stadium to watch Babe Ruth play. Etc.)
