This isn't supposed to be implemented now: these are all pilot studies to see if - in the future - UBI makes sense. We don't yet know whether automation will replace most jobs (I'm of the opinion that it will), but if it does, spending all that money on making sure everyone can buy their food and pay rent becomes worth it. Right now, funding the things you listed does seem to make more sense, but this will change if the job market starts getting smaller and smaller.
