Gold while leveling

I seen the news on the website and wanted to ask, how will it work on people leveling and questing?
When someone is playing a game they have objectives like the flying skill for example.
How can you take gold from people accumulating it for something?
I understand people that have everything and are just toying with their money.
Me for example i take months to reach outland and icecrown because i do all quests and take time on my journey and experience everything.
How can you half my money and say "spend before this date", spend on what? Food and drinks?
I intend to use my money but i will do so when i need to, not when you decide it, it is just wrong!
You should think about this and come with another way, maby apply that reduction on players with more than X amount (20000), since some things are expensive from vendors.
You cant take money from someone accumulating it for something worth 20000, imagine it took that person 2 months, half it to 10000 and make the player go earn it again?
I am very worried because i take a long time doing my things, picking up everything, it took me 3 days to get my first bag with 10 slots, if i would have been caught in that "date" i would had to wait 6 days for my bag.
Please reconsider, because i am playing right now on this server, accumulating my money for my future, not for the moment or before january.
