Wow, that's a ridiculously silly idea.

1) Markets aren't magic coordinators, they take large amounts of human effort to maintain in a functional state. Your system would destroy productivity because it would require a huge increase in market oarticipatio

2) Economic activity needs stability and your system would almost entirely eliminate that.

3) Markets require information to function accurately so to constantly have accurate markets for everything means that you have completely eliminated privacy.

4) Price is not the only important aspect is many transactions. Reputation matters and this system would result in the inability to trust any economic partner because their assets could be bought at any time.

5) You would still need to have massive government regulation to prevent fraudulent collusion. Lets say you seriously underprice your assets to avoid taxes and whenever someone moves to buy the asset, you have a friend who would bid on it until they win. That friend can then sell the asser back to you. Now raise this basic idea by the power of the massive legal and financial efforts that have histoy been put into tax evasion and you have a regulatory problem that dwarfs existing tax enforement problems.

So you would basically tax stability while creating tools that would enable massive fraud and speculation.
