Landlords do provide services: property maintenance and not having to worry about selling the place when you leave. Are landlords paid way too much for these services? Hell yes. That's more an issue of inadequate supply though, in my opinion.
Similarly, ticket scalpers provide a service, but not to concert goers. Scalpers absorb risk on behalf of the venue/performer. That's why venues, who could absolutely shut down scalpers, don't. Still scummy as hell, but don't absolve the venue of guilt too.
There are some pretty significant differences, but you do you.
And since I noticed the disingenuous responses to the other person saying this already, I'm excited for people to respond to this comment by fallaciously assuming I indicated either of these was better or worse than the other. I said they're different.
Those ticket scalpers and land lords are providing an economic service to you by taking the risk that they miss the show or have to pay their own mortgage! It's a very useful service for you!
Hurr durr landlords bad, let me live on your property for a penny even though you had to spend money to create the acquire the property in the first place!!
