Bitcoin mining requires special devices (ASICs). These ASICs would lose their value if Bitcoin lost its value. Given this fact, why would anyone rent them out, or rent out the hash power?

Aside from Satoshi's hoard.. there's also just regular destruction. Units can be mined and then permanently lost. The system has a limited number of units that can be generated in total and no mechanism to replace the lost units.

Why is this not a long term problem for bitcoin?

If your hash power typically translates to $X per day and someone offers you 2X $ to rent the hash power for a day, I suspect most people would rent them out

It's divisible down to 0.00000001.

If that ever became a significant issue I imagine users would be happy to increase the precision via a fork.

LN supports sub satoshi (i.e. higher precision) payments on L2.

If you're talking about the numbers getting super small and being unwieldy, most fiat currencies have the opposite problem of the numbers getting super large, they just redenominate every now and then.

Profitable mining does. If you’re looking to make money, you need ASICs. If you’re just looking to disrupt the network, e.g. for military purposes, commandeering a cloud or two would do.

Because the units are highly divisible and the divisibility can be increased easily if it becomes necessary.

When someone loses/destroys bitcoin, they are effectively donating the value to everyone else who still holds bitcoin.

Infinitely divisible

No; The ASICs are orders of magnitude faster and more efficient per dollar. Every GPU on earth couldn't touch the bitcoin hashrate.
