It punishes. You don't punish people for being too slow, instead you reward them for being fast. Punishing people for playing your game, makes them not want to play.
Instead, i would suggest two changes which work well together.
-The first is a static hardcap on stats and skills that increases every day by 5,( or whatever you want) starting at 100. So after a year the most you could see is 1975 in one stat or skill. This cap slows everything down a little bit. The longer the world goes, the higher Q curios and food there are. So the "gap" between pro's and noobs is easily kept closer, so the increasing cap won't hurt so bad/
This especially helps in the early world, where the behemoths are racing to make titans, now they gotta take it a bit easier, and makes casuals and noobs feel like they have a chance.
The second is an idea ctopolon3 wrote. Which yet again closes the gap between noobs and pro's even more

mb just implement FAT system (like hunger, but permanent)
<100 stats 300% FEP
<250 stats 200% FEP
<700 stats 100% FEP
<2500 stats 80% FEP
<10k stats 50% FEP
>10k stats 25% FEP
Combined together, on paper it seems good.
This is how you close a gap without punishing people, without feeling like you are wasting resources just to not lose your stats.
