I have never trekked there so it is hard for me to say anything from personal experience on this topic. However, If you talk about safety, well people get eaten by bears in the US and in Canada, people get kidnapped in South America, yet you dont have a law saying you have to be accompanied by a shot gun carrying ranger, nor are you banned from back packing in Columbia. You are adviced about the objective hassards thats it. This is why I think it is just to cash in.
It is understandable that they want to make more money on it but do you think that this might actually deter soloist to go there? Its not going to increase tourism thats for sure. Presummably one of the attracting factors to Nepal is the wide open spaces which we struggle to find in our native countries. I think they are shooting themselves in the foot.
I hate being told what I can and can't do
