Disadvantages of using a guitar (with plugins) as a bass, vs buying an actual bass?

I want to add bass to my tracks, and I'm wondering whether I can use my guitar, with plugins, as a bass?

In the spirit of saving money (and minimalism - I live in cramped apartment), I was wondering if it would be a big disadvantage to forego buying an actual electric bass (like a Squire Jazz), and just use a guitar with effects / vst's / etc to sound like an actual bass.

Wondering how close I can get to achieving a "bass" sound with my guitar and plugins?

Or would it be much better just to buy an actual electric bass?

I think you should buy an actual electric bass

To lower the pitch of your guitar by one or two octaves, you may make use of pedals or plugins that alter the pitch of the instrument. A lower, bass-like sound will be produced as a result of this. Additionally, pitch-shifting effects are included in a great number of digital audio workstations (DAWs) pizza tower

You can use pedals or plugins that change the pitch of your guitar to reduce its pitch by one or two octaves. This will result in a sound that is lower and more bass-like. Additionally, a large percentage of digital audio workstations come with pitch-shifting effects.
