I think the ability to store money in houses should be removed.
Even though that this is a big step forward for Argonath in IV:MP, I think it should be removed. The main reason for this is that the sever would be much better off without. With a script such as this there is no role play, you simply grind your earnings off of fireman missions and selling drugs so that you can get a nice car and store it away in your house - that sounds really boring to me.
If the ability to store money was removed, it would spur players to open businesses specializing in storing peoples items and cash. This business is called a bank. Players would create banks to compete with each other and before you know it, you'll have a competitive market but most of all players role playing and creating there own businesses. With all the money that these smart bankers will get from their business, they may even invest it in other business, markets and most importantly loans and soon you'll have a way for players to get money and become even richer, with the ability to actually role play instead of using some commands.
A prime example of who can benefit from the removal of the script is my company Gruppe Sechs and Lucchese Bank, and I'm sure many more people will seek the benefits and there will be a competitive market with many businesses to choose from.
I'm not saying the script is bad, but what I am saying is that there should be less scripts and more player interaction and I think the removal of this script will do that and get people off their backsides and actually do something with their time rather than driving around broker showing off their Turismo.
