That would 100% ruin the game. If it cost the same DEC as the burn value people would buy 25, get at least one GF, burn everything and be net positive in DEC. That would be infinite DEC production and make everything worthless very quickly.
Even if the price was close enough to burn value where this couldn't be done, that would not be good. There needs to be a risk, otherwise everyone gets it and it's not special at all. I'm not one of those that thinks scarcity is what makes this game good but people need to make choices and that wouldn't be a choice at all.
