These can be changed and you can be charged under other crimes which may have different statue of limitations. When the government decides they want you in prison, it doesn't particularly care how it does so. Tax evasion, drug trafficking, funding terrorism, CSA changes, weapons smuggling, or RICO or country equivalent, they'll use which ever seems easiest to get you.
For a buyer, this isn't as big of a deal because you won't have that level of target on your back, but for anyone running a marketplace I don't think statute of limitations will protect you once they figure out who you are.
