The impact of missing TRIM depends a lot on your usage. When the FS starts to reuse blocks from delete files, performance starts to go down because the SSD doesn't know that part of the block can be discarded and will have to do extra work to keep that unused part intact (as Bengie explained in more detail in his answer).

So if you mostly use big files, the impact will be negligible because the FS won't use partial blocks very often.
Or if you don't delete files often, the impact will be negligible because there isn't many blocks to partially reuse.

But think of it, if TRIM was added, it's not just for the fun of it, people saw the performance degradation first. Just read the comments on the web before TRIM was added. Just read the benchmarks when the first drives with TRIM came out. Yes some user will never notice it, but that doesn't mean that nobody does and that TRIM isn't useful.

A good garbage collection can't replace TRIM. Overwritten blocks are not the only ones that can be GC'ed. There is also the blocks from deleted files. And unless the FS uses those blocks first (which any recent filesystem will avoid to do to prevent fragmentation on hard-drives), they will eventually use a significant amount of the SSD and kill the drive performance.

And worse, some modern filesystems use "copy-on-write", so no data is ever overwritten (from the SSD point of view) the SSD performance will drop even more quickly.

"I feel like saying something to her right now, I should say it." - Good.

"I want to have sex with you" - Yeah, I'm sure it will work out well.

Any present actions have future consequences. Not thinking of the future means you ignore the consequences. That can't be a good thin.
As in pretty much everything in life, moderation is key. Don't over-think things that you end up never doing anything. But you still need to think things a bit. ("There is a time for thinking, and there is a time of acting")

The other reason for over-thinking is negative target fixation where one focuses too much on the possible obstacles, ending up scaring oneself too much to act. Fix your mind on where you want to go, keeping a peripheral view on possible obstacles.

"Direct rendering" != "Hardware acceleration".

Correct me if I'm wrong but:
- "Direct rendering" = decode the data directly to Video buffer. Otherwise the data needs to be decoded to a RAM buffer which then needs to be copied to the Video buffer to be actually displayed.
- "Hardware acceleration" = use the GPU for decoding (because a GPU is usually way faster than the CPU for this kind of work).

So you can have "direct rendering" without the "hardware acceleration" (and vice-versa though it's unlikely to happen in practice).

So how exactly would passing a law that basically codifies current practices cause job loss?

1. The legislation passes
2. People get angry at their ISP and set their HQ on fire
3. The ISPs build bigger meaner bunk^H^H^H^H HQs which requires manpower
=> more jobs

1. The legislation passes
2. The ISP demands their protection money
3. The CEOs and other members of the boards become richer
4. They buy bigger houses
5. They requires more maids and gardeners
=> more jobs

1. The legislation passes
2. The ISP demands their protection money
3. The customers become poorer and can't pay their bills
4. The customers are evicted
5. The customers now homeless lose their jobs
=> more jobs (for the others)
6. The customers get depressed and kill themselves
7. They are buried or cremated
8. Graveyards and crematoriums flourish
=> more jobs
