Except for one thing. NASA is still doing business. NASA still can use the Russian rockets to reach the space stztion. I believe NASA has directed funds to private firms.
So, no, I see no harm to this country. Matter of fact, I am not a fan of the Feds doing the deciding what money they took from the public is used for given who pays most of the money to the Feds.
Seems to me that the Rich are in the Space business so why make them richer?
