Maybe buy thousands of houses and donate them.

You do understand that the number of houses in the world is finite? The price of houses would skyrocket if someone attempted to buy up all the properties the the entire world.
According to recent data, there are around 16 million vacant homes in the United States, including both houses and apartments. Meanwhile, an estimated 770,000 people in the country are experiencing homelessness on a given night, based on the latest nationwide count in January 2024.
Are those homes for sale? Is a homeless dude from LA willing to move to the middle of nowhere to claim his "free house", or would he rather continue to collect his foodstamps and use the local McDonald's free wifi with his stolen smartphone in his tent on the street?
These are great questions, they should all be asked. Also it's good we figured out that there are enough empty houses for everyone.
