What if my trust or business buys it? My trust/business is a legal individual that can be passed down to other owners over time?

You'd be in breach of the terms.

It's usually legal to breach terms.

How so? Companies and trusts are legal persons, just like anyone else...

That transfer would breach the term prohibiting transfer.

It's not a transfer. If a trust owns a game, then the trust owns the game. A transfer of trust is not a transfer of ownership of the trust's property.

Now, moving a steam account into a trust might be a breach, if they care. Even using a trust to buy a game might also be a violation of some form, perhaps, buried in the toc.

But the trust itself is a legal entity and it can own things. Just because the people behind the trust changes doesn't mean it was a transfer on the public side of the trust.

The trust won't own the game.

Morever, it can't happen. Accounts are non-transferrable.

Right at the top, actually. GOG, not Steam: "This license is for your personal use."

The account isn't the software. Software are files.

"GOG content" is the software.

From a purely technical perspective, gog offline installers make it trivial to preserve your collection.

It may not be legal, as I said.
