In Fable 3, Reaver is a pretty nasty person: the Hero personally sees him murder a worker in an intentionally slow and painful way for example, and he tries to get the Hero and Page killed in the Mansion.
So, how come the Hero will seemingly happily tolerate Reaver in their court for the year, once they're the monarch, with player having no option to bring him to the justice? And why nobody, for example Page, demands him to be punished (unless I remember wrong and someone does but it leads to nothing)?
Sure, Reaver runs the industry, but certainly a replacement could be found, especially after a good Hero doesn't let him follow his exploitative, murderous management style. Being useful doesn't prevent the player from choosing to have Logan executed, either.
Obviously, I'm looking for an in-universe explanation. I haven't read any of the Fable books, so perhaps they have some semi-plausible explanation?

Out of universe, crappy writing and Reaver being a developer favourite that Lionhead wanted to keep for a sequel. But that's off topic and not the answer you want.
In universe, there are two reasons. First, he's wealthy and has a huge amount of political power. If the hero tried to have him executed and/or confiscate his industries, he has more than enough resources to rebel. Whether or not he would win is irrelevant- the result would be another civil war which would leave Albion too weak to defend itself.
Second, he's centuries old, hasn't aged and is a Hero. Notice how tall he is? He's capable of earning and spending experience and has probably been doing so since Fable 2 where he was already the Hero of Skill. One on one, he's more than a match for the player.
