Help me understand this travel culture (No hate, just trying to understand)

I have always been curious about this.
In Southeast Asia, more and more of such tourists seem to be funding their travels by busking, selling sketches, or asking locals to sponsor the next part of their journey. (Note: local artists and buskers need permits to do so. When tourists do it, they’re bypassing regulations and permits).

I have no issue with travelling on a budget. But I do struggle to understand asking the locals to help fund a holiday, when we ourselves are slogging hard to make a living?

I know this definitely doesn’t represent everyone as there are also wonderful travellers. It is just sad that a small group is giving everyone else a bad name.

How is this viewed back in your country? Is it considered normal, or is it frowned upon if tourists/locals do the same there too?
