Sorry but this is an ignorant take of someone who I presume does not own property. I would have thought similar until we bought a house. Some costs that a renter never thinks about: property taxes, home insurance, flood insurance, leaky roofs, flooded basements, mold remediation, HVAC system replacements, the list goes on. If you think a landlord buys a house and never has to put another dollar in, you are on crack.

If you are a landlord you face plenty of other risks - time between tennants, you incur all the expenses and none of the revenue. Ditto if your renter stops paying and it takes you months or years to evict them. Or your tennant does damage to your property that their security deposit doesn't come close to covering.

On top of all that, there are real risks of asset decline. Just because that hasn't happened recently in most places doesn't mean it won't happen. I can name 5 plausible scenarios under which my house ends up never being worth what I paid for it.

It seems to me that you and others claiming that being a landlord is free money just have zero idea of what it actually takes.
