After the merge will tokens on the consensus layer have the same functionality and potential uses as tokens on the execution layer?

So I am trying to understand how the flow of funds on Ethereum will change after the merge.

https://www.bloxstaking.com/documents/eth2/

In the article above they state that "All ETH deposited onto the Beacon Chain in Phase 0 is from a one-way transaction to the deposit contract. A deposit of 32ETH is required to set up a validator. Note that ETH cannot be withdrawn until later phases."

So my question is as follows, will funds on the consensus layer serve any purpose other than setting up a validator 2 or 3 years after the merge is finished. For example, will there be Uniswap_execution_layer and Uniswap_consensus_layer. Are people going to be moving and using funds on both the consensus layer and the execution layer in the same way that people currently use their funds on Ethereum today. Basically, with respect to flow of funds and use of funds, will it be the same as tokens on Ethereum vs tokens on Aribitrum where use cases are the same.

Alternatively is it the case that over time there will be specific types of activity on the consensus layer that is different to the activity on the execution layer by design, i.e. only activities related to staking, validation and validator rewards are on the consensus layer.

Thank you for your help!
