How will miners/transporters be paid when no more BTC can be created?

Correct me if I'm wrong, but:

The rate at which BTC can be produced, a mining, gets halved every few years.

Either halving will keep happening until no one can be rewarded, or the supply runs out because all the BTC will be mined.

When this happens, how will BTC be move-able if no one will move it without getting a mining reward from the blockchain? In order for BTC to be transmitted, it requires someone to still be mining BTC, right?

I know this has been asked before but I remember reading answers from years ago and people kept commenting on what they think "should" happen, as in, their personal philosophy, and not what WILL happen as per the properties of the blockchain, or any laws that apply.
