Some people have already replied that you might not be able to trust everyone with your password, but that's only one of the problems. The other problem is that although your heirs may be able to physically read the password from your sealed envelope and type it in, just typing in the password won't make your access authorized. Trying to download the deceased's ebooks, music, or apps would be piracy, and even just revealing that you accessed the account (by trying to use the information in it in a billing dispute, or to take it to the press if it is whistleblowing in nature, for instance) could subject you to a selectively prosecuted hacking charge in court to get you to shut up.
And even if you don't actually get in legal trouble for accessing the account, companies could use the illegal nature of the access to refuse to do things that they would do upon request of the account owner, such as closing the account (if you want it closed), leaving the account open (if you want to keep paying for it), or restoring or sending you a backup.
