I'm not an expert too, and maybe, but from my point of view, no, everything is based on game theory.

All parties must be in relative equilibrium to avoid incentives going to the side of one party.

Obviously, everyone wants to tip the balance to their side.

So, a network with higher hashrate power is a secure network to a secure network that will want to come from those who do not want to lose their value, so that should incentivize whoever wants the reward of mining to invest, and the investment is skin in the game.

So, it will be expensive to mine to anybody? It will depend on is the reward is appetizing enough for you.
