Honestly, Sony should just retroactively bill consumers for inflation. Since $60 in 2016 is worth almost $89 today, they should charge all the people who bought the game back then a $29 price adjustment. It's the the only fair thing to do for.
If consumers don't like that option, an alternative can be a perpetual $5/year subscription that additional provides in-game stickers.
Another alternative is to just buy the used games and play them on the old consoles.
