Are you suggesting we not save lives so that we can avoid some unrealized fear of overcrowding?

Suppose humanity attains indefinite life spans in the near future. Would you then advocate murder in order to save space?

Should we outlaw antibiotics because they save lives, and those lives take up resources?

I find this argument both unimaginative (improving technology changes the nature of our challenges) and repulsive (it's advocating murder through inaction).
