A Beacon is in no way worth so much, Beacons can only be placed in towns which drastically lowers the price of it, maybe like 20 - 30k is a better price.

20 - 30k is a better price.

If you think that hunting and killing enough wither skeletons to make a wither and then kill it is worth 20-30k then the amount of people who will do it will be basically zero as mining will be far faster money and then as people earn more money and create towns and want beacons there will be no one to supply them as it is not worth the effort to get them. Think about what you are saying you are valuing about 4 hours of work at about 5-7ish k per hour. Think of how ridiculous that is. There is a difference between something you would like to pay (like I would love to pay 7 nbz for diamond ore) and the actual price of an item. I highly doubt people will sell diamond ore to me and I highly doubt people will sell beacons to you. But if you want to sell them to me for that price I have cash for 11 and I can liquidate my diamonds to buy another 100+ if you'd like to set that up =)

Fun fact, wither skulls are considered Rare Drops on the wiki!

 don't know the actual price, which is not 100k+

You're right, some people don't know the actual price.
Some people need to know the economy and difficulty of items to obtain =)
