Even if there were actually enough services in place they tend to be designed to be a painful and inconvenient as legally possible to access.
So it would be technically true to say there enough resources for services - be have those resources actually been allocated? It could technically be true that the services exist but how accessible are they? Are we taking the words of the politician who doesn't rely on the systems to use them, the worker in the ground floor in charge or executing the system, or the people who have to use the systems? One of the most egregious hurdles a homeless person may face when applying for and accessing services is that they don't have a physical address that exists in a database. That means if they don't have a idea it's that much harder for them to prove who they are to get an Idea, without an idea it's that much harder to access services. They might not have a reliable way to receive correspondence from the government services and there's not enough social workers, resources allocated to social workers to help the people out.
Retouching on my initial statement, there are those ok power who believe to their core that receiving charity (or taking advantage of any government program) should be hard and painful in proportion to how desperate you are.
