So your theory is that we can actually stop working and start getting UBI and things will turn out fine?
Whether a basic income will address those problems is an open question. It may have a net positive, neutral, or negative effect depending upon the collective psychological response. In addition, how one views the outcome will depend upon their perspective. Suggesting that an UBI will result in people not working is a misleading ideological statement that has no basis in evidence. We simply don't know what the outcome will be. Even studies that indicate positive outcomes are limited by the scale of the implementation.
Besides, it's probably best to look at UBI through the lens of political stability, rather than social well being or economic outcomes.
EDIT: added a very important "not".
